Glance Unit Tests
Glance doesn't have unit testing built into it. Some parts of the program are going to be very hard to test (because it's got a lot of file access and complex output) but I want to include more unit tests where I can to cut down on the chances things will break and not be detected when I make changes.
I'll put in some more notes and detailed plans once I've done some evaluation of where it will be least painful to start this effort.
