worked on 3 methods

1. checkIfIsEdge sends room numbers to checkEdge in theGraph
2. setBlockedWalls sends room Nodes to blockWall in theGraph
3 calcReachableRooms only does stuff in Driver03(which ill move some stuff to theGraph) and so far works for nogas picture example(havent done any other testing for it yet)
NOTE: Also, nogas file isnt the same as his example picture, so ill upload the file that is the same as his picture
