   * Root of the component tree which encompasses a set of related

   *
   * <p>
   * The <code>View</code> component ties together all the components and
   * configuration of the User Interface for a piece of functionality. In Rice

   * instance.

   * <p>
   * The view template lays out the common header, footer, and navigation for the

   * common script files and style sheets, along with optionally rendering a form
   * element for pages that need to post data back to the server.
