not a bad idea, but there is a bit of a problem - templating all these classes 
is going to result in code bloat. it'll probably double the size of all the 
libraries. besides, then i'd have to rewrite all my generation routines to 
spit out templates :) oh - using smart pointers might also get in the way of 
the class hierarchies. i'm not entirely sure how i could get around that.

actually, the memory management isn't too hard. there's really only a couple 
places where references need to be addressed. we can also use Qt signals to 
help out. somehow. anyway, it shouldn't be too bad. as we figure out where 
we're leaking memory, we can tweak the generator, rewrite the metamodel and 
test it again.
