Issues:
  a)
 renderMain and renderBuoy should return the coordination system integer 
 which is these frameCS.

  b)
 renderMain and renderBuoy need to match with specified object ehich can 
 be then used from bouymanager.

Anyway I don't know how to do it with no hassle at all with buoys. 

The AbstractAnimationNode class was something where only needed to say 
super(foo) if animation is conserned but I keep thinking of all 
possibilities.
