Create a bird's eye view of a project's source code.
This does a git-blame on each line of a project's source code and then generates a color coded image of the source text for the entire project.
Usage:
Generate an image of the latest birsdeye git repo itself: python birdseye.py
Generate a movie of the last 20 git commits of the birdseye repo: python birdseye.py --movie --revs 20
Generate an image of another git repo: python birdseye.py --target ../other_repo
