//
//   This code works very simply.  It creates a new
//   js variable called BrowserDetect.  This variable
//   has 4 properties:
//     browser = browser name
//     version = version of the browser
//          OS = the operating system of the user
//   supported = "v" is returned for visual editor support
//               "c" is classic wizard only
//
//   to get everything to work, just include this javascript file in your code
//   before you use the BrowserDetect variable.

  var BrowserDetect = {
