Add inline code documentation to module

I don't know if this is something I'm supposed to submit a ticket for, but as I was digging around in the module's code I noticed a severe lack of docblocks and probably other inline comments that would help developers understand what's going on. Personally, I would be happy to commit some basic docblocks to indicate which of your functions are implementing hooks. But mostly I just thought I'd leave this thread here so you can keep it in mind for when you have time to add more documentation to your module, I guess.
