nonroads, and stoplights. These still need to be implemented before
anything can be tested.
Fixed the scanner reading from the filename instead of the actual file
Merge remote-tracking branch 'upstream/master'

Implemented getNextTile method
Added some unused functionality to traffic lights, and created a traffic
