[Compiler-sig] More jython progress.

Perhaps I'm just getting hung up on definitions.

I was translating "class instance attributes" as "object attributes"
since an "instance of a class" is called an "object".  Now that I
think about it, it could mean "attributes which are stored in
classes".

If I can add attributes to the objects which make up the tree, then
great!  I don't put any attributes in a class.

Slower is not better.  I prefer to work in python, even if I have a
few more rules.  If it gets slower, I'll be forced to go to C.

I tried to work with the C version of the AST for a few hours.  It
wasn't pleasant.
