//  2007-NOV-15 : Script updated from milkytreat's v0.3 by Tom Higgins (tom@unity3d.com)                              //
//                - it's now compatible with both Unity 1.0 and 2.0 content                                           //
//                - it now uses 'ut' instead of 'otee' in the code                                                    //
//                - there are changes to the parameters that are provided when creating the UnityObject versus those  //
//                  that need to be added by calling addParam                                                         //
//                - for Unity 2.0 content this script now takes advantage of the fact that the user doesn't need to   //
//                  quit the browser when installing the Unity Web Player                                             //
