 *
 * @description
 *
 * You can attach a context object to the `EmbeddedViewRef` by setting `[ngOutletContext]`.
 * `[ngOutletContext]` should be an object, the object's keys will be the local template variables
 * available within the `TemplateRef`.
 *
 * Note: using the key `$implicit` in the context object will set it's value as default.
