 /**
  * Reinitialise the application and execute the handler without redirecting the browser
  *
  * This is a useful function to avoid having {@link Handler} classes grows unmaintainably
  * large, without the invonvenience of redirecting the browser. There is a peformance hit
  * because the application is reinitialised, and the user is revalidated, however it is
  * not extreme. 
  *
  * The important thing to remember when using the execute() method is that if the user 
  * refreshes the browser, the handler that was executed first by the application will be
  * executed again, not any handler that has been executed using the execute() method.
  *
  * If you need to redirect the browser url use {@link Application::redirect()}
  *
  * @param handler - the handler class name to execute
  * @access public
