/**

 * Based on the expressinstall.as class created by Geoff Stearns as part

 * of the FlashObject library.

 *

 * 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

 * and this file at the following URL: http://blog.deconcept.com/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.
