 * Use this file to invoke the Macromedia Flash Player Express Install functionality

 * This file is intended for use with the FlashObject embed script. You can download FlashObject

 *

 * Usage: 

 *          var ExpressInstall = new ExpressInstall();

 *          

 *          // test to see if install is needed:

 *          if (ExpressInstall.needsUpdate) { // returns true if update is needed

 *              ExpressInstall.init(); // starts the update

 *          }

 *

 *	NOTE: Your Flash movie must be at least 214px by 137px in order to use ExpressInstall.
