   * Implements lowercase transforms to text.

   * ### Example
   *
   * In this example we transform the user text lowercase.
   *
   *  ```
   * @Component({
   *   selector: "username-cmp",
   *   template: "Username: {{ user | lowercase }}"
   * })
   * class Username {
   *   user:string;
   * }
   *
   * ```
