Fix class definitions

[chuck1]

Currently function attributes of class objects are not bound.

Current method:
Class source code is used to make my FunctionType which is then passed to my build_class method. The build class method executes the class source and recovers the locals. It then constructs new class source code using those locals.

Ideas:
Temporarily have my make_function methof return regular function and see it that works, implying that my build_class method works.

Try deriving from types.FunctionType for functions or wrapping my FunctionType in a regular function type.

Try types.new_class

Experiment with creating a global function and assigning it to a class to create a class function.
