  // Purpose: This is where the javascript cusomot functionss are located.  This file 
  //          currently contains two functions:
  //
  //          1. A callback function thatfor restarting bitcoin, and shutting down the 
  //             device. The call function performs AJAX calls to  jquery-ajax.php where 
  //             the system  actions are taken. 
  //          2. An anonymous function that provides the javascript responsible for
  //             keeping the tooltip text within the disply.
