      This is a limited shim for ShadowDOM css styling.
      https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles

      The intention here is to support only the styling features which can be
      relatively simply implemented. The goal is to allow users to avoid the
      most obvious pitfalls and do so without compromising performance significantly.
      For ShadowDOM styling that's not covered here, a set of best practices
      can be provided that should allow users to accomplish more complex styling.

      The following is a list of specific ShadowDOM styling features and a brief
      discussion of the approach used to shim.

      Shimmed features:

      * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
      element using the :host rule. To shim this feature, the :host styles are
      reformatted and prefixed with a given scope name and promoted to a
      document level stylesheet.
      For example, given a scope name of .foo, a rule like this:

        :host {
            background: red;
          }
        }

      becomes:

        .foo {
          background: red;
        }

      * encapsulation: Styles defined within ShadowDOM, apply only to
      dom inside the ShadowDOM. Polymer uses one of two techniques to implement
      this feature.

      By default, rules are prefixed with the host element tag name
      as a descendant selector. This ensures styling does not leak out of the 'top'
      of the element's ShadowDOM. For example,

      div {
          font-weight: bold;
        }

      becomes:

      x-foo div {
          font-weight: bold;
        }

      becomes:


      Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
      selectors are scoped by adding an attribute selector suffix to each
      simple selector that contains the host element tag name. Each element
      in the element's ShadowDOM template is also given the scope attribute.
      Thus, these rules match only elements that have the scope attribute.
      For example, given a scope name of x-foo, a rule like this:

        div {
          font-weight: bold;
        }

      becomes:

        div[x-foo] {
          font-weight: bold;
        }

      Note that elements that are dynamically added to a scope must have the scope
      selector added to them manually.

      * upper/lower bound encapsulation: Styles which are defined outside a
      shadowRoot should not cross the ShadowDOM boundary and should not apply
      inside a shadowRoot.

      This styling behavior is not emulated. Some possible ways to do this that
      were rejected due to complexity and/or performance concerns include: (1) reset
      every possible property for every possible selector for a given scope name;
      (2) re-implement css in javascript.

      As an alternative, users should make sure to use selectors
      specific to the scope in which they are working.

      * ::distributed: This behavior is not emulated. It's often not necessary
      to style the contents of a specific insertion point and instead, descendants
      of the host element can be styled selectively. Users can also create an
      extra node around an insertion point and style that node's contents
      via descendent selectors. For example, with a shadowRoot like this:

        <style>
          ::content(div) {
            background: red;
          }
        </style>
        <content></content>

      could become:

        <style>
          / *@polyfill .content-container div * /
          ::content(div) {
            background: red;
          }
        </style>
        <div class="content-container">
          <content></content>
        </div>

      Note the use of @polyfill in the comment above a ShadowDOM specific style
      declaration. This is a directive to the styling shim to use the selector
      in comments in lieu of the next selector when running under polyfill.

     * Minimum amount of binding slots required in the runtime for style/class bindings.
     *
     * Styling in Angular uses up two slots in the runtime LView/TData data structures to
     * record binding data, property information and metadata.
     *
     * When a binding is registered it will place the following information in the `LView`:
     *
     * slot 1) binding value
     * slot 2) cached value (all other values collected before it in string form)
     *
     * When a binding is registered it will place the following information in the `TData`:
     *
     * slot 1) prop name
     * slot 2) binding index that points to the previous style/class binding (and some extra config
     * values)
     *
     * Let's imagine we have a binding that looks like so:
     *
     * ```
     * <div [style.width]="x" [style.height]="y">
     * ```
     *
     * Our `LView` and `TData` data-structures look like so:
     *
     * ```typescript
     * LView = [
     *   // ...
     *   x, // value of x
     *   "width: x",
     *
     *   y, // value of y
     *   "width: x; height: y",
     *   // ...
     * ];
     *
     * TData = [
     *   // ...
     *   "width", // binding slot 20
     *   0,
     *
     *   "height",
     *   20,

     * This array represents the DOM schema. It encodes inheritance, properties, and events.
     *
     * ## Overview
     *
     * Each line represents one kind of element. The `element_inheritance` and properties are joined
     * using `element_inheritance|properties` syntax.
     *
     * ## Element Inheritance
     *
     * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
     * Here the individual elements are separated by `,` (commas). Every element in the list
     * has identical properties.
     *
     * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
     * specified then `""` (blank) element is assumed.
     *
     * NOTE: The blank element inherits from root `[Element]` element, the super element of all
     * elements.
     *
     * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
     *
     * ## Properties
     *
     * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
     * by a special character designating its type:
     *
     * - (no prefix): property is a string.
     * - `*`: property represents an event.
     * - `!`: property is a boolean.
     * - `#`: property is a number.
     * - `%`: property is an object.
     *
     * ## Query
     *
     * The class creates an internal squas representation which allows to easily answer the query of
     * if a given property exist on a given element.
     *
     * NOTE: We don't yet support querying for types or events.
     * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
     *       see dom_element_schema_registry_spec.ts

     * A regular expression for breaking a URI into its component parts.
     *
     * {@link http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#RFC2234} says
     * As the "first-match-wins" algorithm is identical to the "greedy"
     * disambiguation method used by POSIX regular expressions, it is natural and
     * commonplace to use a regular expression for parsing the potential five
     * components of a URI reference.
     *
     * The following line is the regular expression for breaking-down a
     * well-formed URI reference into its components.
     *
     * <pre>
     * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
     *  12            3  4          5       6  7        8 9
     * </pre>
     *
     * The numbers in the second line above are only to assist readability; they
     * indicate the reference points for each subexpression (i.e., each paired
     * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
     * For example, matching the above expression to
     * <pre>
     *     http://www.ics.uci.edu/pub/ietf/uri/#Related
     * </pre>
     * results in the following subexpression matches:
     * <pre>
     *    $1 = http:
     *    $2 = http
     *    $3 = //www.ics.uci.edu
     *    $4 = www.ics.uci.edu
     *    $5 = /pub/ietf/uri/
     *    $6 = <undefined>
     *    $7 = <undefined>
     *    $8 = #Related
     *    $9 = Related
     * </pre>
     * where <undefined> indicates that the component is not present, as is the
     * case for the query component in the above example. Therefore, we can
     * determine the value of the five components as
     * <pre>
     *    scheme    = $2
     *    authority = $4
     *    path      = $5
     *    query     = $7
     *    fragment  = $9
     * </pre>
     *
     * The regular expression has been modified slightly to expose the
     * userInfo, domain, and port separately from the authority.
     * The modified version yields
     * <pre>
     *    $1 = http              scheme
     *    $2 = <undefined>       userInfo -\
     *    $3 = www.ics.uci.edu   domain     | authority
     *    $4 = <undefined>       port     -/
     *    $5 = /pub/ietf/uri/    path
     *    $6 = <undefined>       query without ?
     *    $7 = Related           fragment without #

     * Creates a token that can be used in a DI Provider.
     *
     * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
     * runtime representation) such as when injecting an interface, callable type, array or
     * parameterized type.
     *
     * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
     * the `Injector`. This provides additional level of type safety.
     *
     * ```
     * interface MyInterface {...}
     * var myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
     * // myInterface is inferred to be MyInterface.
     * ```
     *
     * When creating an `InjectionToken`, you can optionally specify a factory function which returns
     * (possibly by creating) a default value of the parameterized type `T`. This sets up the
     * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
     * application's root injector. If the factory function, which takes zero arguments, needs to inject
     * dependencies, it can do so using the `inject` function. See below for an example.
     *
     * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
     * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
     * mentioned above, `'root'` is the default value for `providedIn`.
     *
     * @usageNotes

     * `TView.data`. This allows us to store information about the current node's tokens (which
     * can be shared in `TView`) as well as the tokens of its ancestor nodes (which cannot be
     * shared, so they live in `LView`).
     *
     * Each of these slots (aside from the last slot) contains a bloom filter. This bloom filter
     * determines whether a directive is available on the associated node or not. This prevents us
     * from searching the directives array at this level unless it's probable the directive is in it.
     *
     * See: https://en.wikipedia.org/wiki/Bloom_filter for more about bloom filters.

         * check every five seconds.

     * Base class for Angular Views, provides change detection functionality.
     * A change-detection tree collects all views that are to be checked for changes.
     * Use the methods to add and remove views from the tree, initiate change-detection,
     * and explicitly mark views as _dirty_, meaning that they have changed and need to be rerendered.
     *
     * @usageNotes
     *
     * The following examples demonstrate how to modify default change-detection behavior
     * to perform explicit detection when needed.
     *
     * ### Use `markForCheck()` with `CheckOnce` strategy
     *
     * The following example sets the `OnPush` change-detection strategy for a component
     * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
     * after an interval. See [live demo](http://plnkr.co/edit/GC512b?p=preview).

     * <code-example path="core/ts/change_detect/change-detection.ts"
     * region="mark-for-check"></code-example>
     *
     * ### Detach change detector to limit how often check occurs
     *
     * The following example defines a component with a large list of read-only data
     * that is expected to change constantly, many times per second.
     * To improve performance, we want to check and update the list
     * less often than the changes actually occur. To do that, we detach
     * the component's change detector and perform an explicit local check every five seconds.
     *
     * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
     *
     *
     * ### Reattaching a detached component
     *
     * The following example creates a component displaying live data.
     * The component detaches its change detector from the main change detector tree
     * when the `live` property is set to false, and reattaches it when the property
     * becomes true.

     * A ReflectiveDependency injection container used for instantiating objects and resolving
     * dependencies.
     *
     * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
     * constructor dependencies.
     *
     * In typical use, application code asks for the dependencies in the constructor and they are
     * resolved by the `Injector`.
     *
     * @usageNotes
     * ### Example
     *
     * The following example creates an `Injector` configured to create `Engine` and `Car`.
     *
     * ```typescript
     * @Injectable()
     * class Engine {

     * var car = injector.get(Car);
     * expect(car instanceof Car).toBe(true);
     * expect(car.engine instanceof Engine).toBe(true);
     * ```
     *
     * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
     * resolve all of the object's dependencies automatically.
     *
     * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.

    // This function calls the ngAfterContentCheck, ngAfterContentInit,

    // flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are
    // called during a pre-order traversal of the view tree (that is calling the
    // parent hooks before the child hooks) these events are sent in using a
    // post-order traversal of the tree (children before parents). This changes the
    // meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
    // expected nodeIndex which a ngOnInit should be called. When sending
    // ngAfterContentInit and ngAfterViewInit it is the expected count of
    // ngAfterContentInit or ngAfterViewInit methods that have been called. This
    // ensure that despite being called recursively or after picking up after an
    // exception, the ngAfterContentInit or ngAfterViewInit will be called on the
    // correct nodes. Consider for example, the following (where E is an element
    // and D is a directive)
    //  Tree:       pre-order index  post-order index
    //    E1        0                6
    //      E2      1                1
    //       D3     2                0
    //      E4      3                5
    //       E5     4                4
    //        E6    5                2
    //        E7    6                3
    // As can be seen, the post-order index has an unclear relationship to the
    // pre-order index (postOrderIndex === preOrderIndex - parentCount +
    // childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
    // are stable (will be the same for the same view regardless of exceptions or
    // recursion) we just need to count them which will roughly correspond to the
    // post-order index (it skips elements and directives that do not have
    // lifecycle hooks).
    //
    // For example, if an exception is raised in the E6.onAfterViewInit() the
    // initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
    // initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
    // not have their ngAfterViewInit() called but, starting with E7, the rest of
    // the view will begin getting ngAfterViewInit() called until a check and
    // pass is complete.
    //
    // This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
    // indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
    // initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
    // D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
    // When the recursion returns the initIndex will be 7 so E1 is skipped as it
    // has already been called in the recursively called checkAnUpdateView().

                //   imports,
                //
                // In Ivy, things are a bit different. .ngfactory files still exist for compatibility, but are
                // not a required API to use - there are other ways to obtain an NgModuleFactory for a given
                // NgModule. Thus, relying on a side effect in the .ngfactory file is not sufficient. Instead,

     *
     * @usageNotes
     *
     * {@a is-stable-examples}
     * ### isStable examples and caveats
     *
     * Note two important points about `isStable`, demonstrated in the examples below:
     * - the application will never be stable if you start any kind
     * of recurrent asynchronous task when the application starts
     * (for example for a polling process, started with a `setInterval`, a `setTimeout`
     * or using RxJS operators like `interval`);
     * - the `isStable` Observable runs outside of the Angular zone.
     *
     * Let's imagine that you start a recurrent task
     * (here incrementing a counter, using RxJS `interval`),
     * and at the same time subscribe to `isStable`.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *      filter(stable => stable)
     *   ).subscribe(() => console.log('App is stable now');
     *   interval(1000).subscribe(counter => console.log(counter));
     * }
     * ```
     * In this example, `isStable` will never emit `true`,
     * and the trace "App is stable now" will never get logged.
     *
     * If you want to execute something when the app is stable,
     * you have to wait for the application to be stable
     * before starting your polling process.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     tap(stable => console.log('App is stable now')),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => console.log(counter));
     * }
     * ```
     * In this example, the trace "App is stable now" will be logged
     * and then the counter starts incrementing every second.
     *
     * Note also that this Observable runs outside of the Angular zone,
     * which means that the code in the subscription
     * to this Observable will not trigger the change detection.
     *
     * Let's imagine that instead of logging the counter value,
     * you update a field of your component
     * and display it in its template.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => this.value = counter);
     * }
     * ```
     * As the `isStable` Observable runs outside the zone,
     * the `value` field will be updated properly,
     * but the template will not be refreshed!
     *
     * You'll have to manually trigger the change detection to update the template.
     *
     * ```
     * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => {
     *     this.value = counter;
     *     cd.detectChanges();
     *   });
     * }
     * ```
     *
     * Or make the subscription callback run inside the zone.
     *
     * ```
     * constructor(appRef: ApplicationRef, zone: NgZone) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => zone.run(() => this.value = counter));
     * }
     * ```
