/**
 * Class Player
 * 
 * Uses the serverGeneratedUniqueDivId and the mediaCollection to start a player instance.
 * 
 * According to the media inside the mediaCollection the class checks which plugins and
 * media is available. The DOM is also configured according to this, using the domConfiguration
 * object (also adds playerformats and mediaquality to the control panel)
 * 
 * The player tries to use the the plugins in this hierarchy:
 * 1. flash
 * 2. silverlight
 * 3. windows media plugin
 * 
 * The prefs can be safed via session cookie. The cookie prefs are used, if available.
 * Else the best prefs will be choosen automatically.
 * 
 * The underscore is used to declare classes, attributes and methods 
 * as private by naming convention.
