"""
Iterate over all modules in source tree.
Useful as a framework for any portions of a refactoring which need to
be executed for every module. The iterator created by
ModuleIterator() produces (fileName, moduleName) pairs for each python
source file in or below the current working directory. Tools using
this should generally run in cad/src.
Typical usage::
for (fileName, moduleName) in ModuleIterator():
code for each module...
The fileNames produced look like "./directory/Module.py", with a
corresponding moduleName of "directory.Module".
