|        This activate method is called automatically by        |
|        the constructor to cause the applet to start up.       |
|                                                               |
|        Although applets can be added to a web page without    |
|        using Javascript, this method is preferred because     |
|        following Microsoft's loss to the Eolas patent,        |
|        inline ActiveX objects now have to be clicked on to    |
|        be activated.                                          |
|                                                               |
|        This javascript avoids that issue and allows the       |
|        applets to become active as soon as the web page is    |
|        is loaded. (when the applet constructor is called).    |
|        Simply call the applet constructor above and the       |
|        applet will automatically start up and run.            |
|                                                               |
|        Applets should call the onActivate() function          |
|        when they start up in order to notify their            |
|        Javascript wrappers that the applet has started        |
|        and is ready to be used.                               |
|                                                               |
