 * @description
 *
 * Inserts an embedded view from a prepared `TemplateRef`.
 *
 * You can attach a context object to the `EmbeddedViewRef` by setting `[ngTemplateOutletContext]`.
 * `[ngTemplateOutletContext]` should be an object, the object's keys will be available for binding
 * by the local template `let` declarations.
 *
 * @usageNotes
 * ```
 * <ng-container *ngTemplateOutlet="templateRefExp; context: contextExp"></ng-container>
 * ```
 *
 * Using the key `$implicit` in the context object will set its value as default.
 *
 * ### Example
 *
 * {@example common/ngTemplateOutlet/ts/module.ts region='NgTemplateOutlet'}
