    * @param - An associative array of parameters for this player to use when showing.  These can be as follows.
    *
    *    width    - The width of the player.
    *    height   - The height of the player.
    *    id       - The HTML ID of the player.
    *    schema   - The XML schema of the playlist to generate (XML, RSS, or ASX).

    *
    *    All other parameters are the FlashVars used to govern the player.  These can be found by going to http://www.tmtdigital.com/flashvars .
    *
    *    Example 1:  To show a media player that will play the file http://www.mysite.com/videos/video.flv, you would use the following code...
    *
    *       <?php
    *          $params['file'] = 'http://www.mysite.com/videos/video.flv';
    *          $player = new DashPlayer($params);
    *          $player->show();
    *       ?>
    *
    *    Example 2:  To show the default playlist in the playlists folder...
    *
    *       <?php
    *          $player = new DashPlayer();
    *          $player->show();
    *       ?>
