For those who had expressed interest in the new GP Tree Builders, and  
particularly in helping me test them with the existing untyped GP  
code in ECJ and also stress-test them with typed GP code, here they are:





The builders are now looser in their constraints regarding having to  
have nonterminals and terminals for every single possible node type  
-- but they give warnings.  You may need to grab the current CVS  
sources if you can't compile them with the most recent ECJ version  
snapshot on the website -- they may use functions like warnOnce which  
I'm not sure are in the recent snapshot.

I don't know if I introduced bugs when making these changes, and  
there are a lot of changes, so I'm somewhat loathe to put them into  
the CVS tree without any significant testing.  Hence the request.
