/**
 * Represents an Angular View.
 *
 * <!-- TODO: move the next two paragraphs to the dev guide -->
 * A View is a fundamental building block of the application UI. It is the smallest grouping of
 * Elements which are created and destroyed together.
 *
 * Properties of elements in a View can change, but the structure (number and order) of elements in
 * a View cannot. Changing the structure of Elements can only be done by inserting, moving or
 * removing nested Views via a {@link ViewContainerRef}. Each View can contain many View Containers.
 * <!-- /TODO -->
 *
 * ### Example
 *
 * Given this template...
 *
 * ```
 * Count: {{items.length}}
 * <ul>
 *   <li *ngFor="let  item of items">{{item}}</li>
 * </ul>
 * ```
 *
 * ... we have two {@link ProtoViewRef}s:
 *
 * Outer {@link ProtoViewRef}:
 * ```
 * Count: {{items.length}}
 * <ul>
 *   <template ngFor let-item [ngForOf]="items"></template>
 * </ul>
 * ```
 *
 * Inner {@link ProtoViewRef}:
 * ```
 *   <li>{{item}}</li>
 * ```
 *
 * Notice that the original template is broken down into two separate {@link ProtoViewRef}s.
 *
 * The outer/inner {@link ProtoViewRef}s are then assembled into views like so:
 *
 * ```
 * <!-- ViewRef: outer-0 -->
 * Count: 2
 * <ul>
 *   <template view-container-ref></template>
 *   <!-- ViewRef: inner-1 --><li>first</li><!-- /ViewRef: inner-1 -->
 *   <!-- ViewRef: inner-2 --><li>second</li><!-- /ViewRef: inner-2 -->
 * </ul>
 * <!-- /ViewRef: outer-0 -->
 * ```
