/**
   <b>AnimationPlayer usage:</b> \n

   <b>Initialisation</b>: AnimationPlayer::getInstance() does the trick this is
   usually done when initializing a world \n
   <b>Adding Animations</b>: create an Animation the following Way:
   \li Anim* animation = new Anim(); // also use any other Subclass of Animation to initialize this
   \li set some parameters: also see the specific classes for more info
   \n
   if you do not want a specific Animation to be handled by the AnimationPlayer, you have to
   unload it explicitely with animation->doNotHandle();
   \n
   eveything else will be done by the AnimationPlayer itself.\n
