Added a few baseline things to the nameSpacebean to help access items, I'm not sure how we're creating beans based off of the premade classes. Also added the logic that should work for binOps but I wasn't sure how to check for magicMethods in a bean or how we're doing that. So the logic is there just needs the right methods put in there.
Commented out the logic for binOps as it isn't working without knowing how to get if a bean has a magic method
changed a few lines to make it easier to read
Updated the logic in binop to something more inline with what python does. Updated FunDefBean signature to take strings
Added test files for binOps and fixed one assumption in the Walker's visit_binop.
