Hey buddy. I wanted to tell you this before you heard it from someone
else...
I refactored ICG.
Now, it's gonna look a little scary at first. But I promise you'll like
it when you get used to it. It'll be fine. You can trust me. #341
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
