Rotations in SchematicLoader are understandable now. I changed all the code to use transformPoint() and made sure that the rotations in there are correct. Testing shows that rooms are being generated correctly. I also edited portions of the code for clarity and removed some debug prints. The loading process now allows permafabric to generate - it was previously converted into regular fabric of reality. For the moment, the code is stuck to assume that the entry direction is North. I'll remove that constraint in the next commit.
