Grandulate causes issues with import statements in the py file

[zshaheen]

When you have an input Python file with an import statement, the granulate feature doesn't work. The error is TypeError: can't pickle NotImplementedType objects caused when a Parameters object is copied with copy.deepcopy(params). The full error is below.

My guess is that objects of ModuleType aren't pickable. Maybe remove them from the object before CDPParser.granulate() is called?
