* Bug in MapBool::print() fixed, the map was being printed 90 degrees wrong.
* Comments added to pathfinder.h to help other people trying to read the code.
* Documentation updated with new urls and emails.
* I'm still waiting for Michael's acceptance of me using his changes, but i can't reach him, Michael, if you read this, please email me.
