CVS commit by luis: 

Start of associationwidget code.
Implemented as a canvasItem.. altough I think this is thre right thing, I am starting
to think implementing is a an object *containing* a bunch of lines (like in current code)
would be much easier... I dont think it'd be  clean, but it would definetly be easier...
