Module lemon.external.Cheetah.ImportManager

Provides an emulator/replacement for Python's standard import system.

This is a hacked/documented version of Gordon McMillan's iu.py. I have:

  - made it a little less terse

  - added docstrings and explanatations

  - standardized the variable naming scheme

  - reorganized the code layout to enhance readability
