[udig-devel] animation advice

[Jesse Eichar]

2 things.

1.  You can create a LayerAddedInterceptor extension to detect when  
your layer is added to a map... I think it is also called when the  
map is loaded but I may be wrong.  So maybe you should create a  
MapOpening interceptor that adds the listener I'm going to discuss in  
point 2.
2.  You can add a listener to the edit manager to listen to the  
currently selected layer.  and starrt/stop the timer based on that.
