    23   * A Roller specific version of the struts2 Preparable interface.
    24   *
    25   * We only have this because we don't want to use the struts2 Preparable IF due
    26   * to the fact that it is meant to be called much earlier in the interceptor
    27   * stack, namely before our custom interceptors have been processed.  While
    28   * that may make sense in some cases, typically we want to prepare things based
    29   * on the user or weblog that we are working on, so it's often of more use for
    30   * us to prepare *after* our custom interceptors have been processed.
    31   *
    32   * So, this duplicate of the struts2 Preparable interface is here so that we
    33   * can leave the default struts2 prepare() logic in place for any actions we
    34   * may define that want to use that, but also provide a prepare option that is
    35   * executed at the very end of our interceptor stack, just before the action
    36   * method is executed.  This way our custom prepare method can make use of 
    37   * anything our custom interceptors provide.
