Code commented

I have just finished commenting code for maintainability. I have been using #TODO: for an adhoc to do list throughout the code. This is especially useful as it appears as a different colour (purple) in NetBeans 6.5 which makes it easy for me to skin the code to look for things to fix up that I would have otherwise forgotten about but didn't have the time (or couldn't be bothered) at the time to fix.
