this incorporates some of @chintal's layers.py changes PCB.from_directory() simplifies loading of multiple gerbers the PCB() class should be pretty helpful going forward... the context classes could use some cleaning up, although I'd like to wait until the freecad stuff gets merged, that way we can try to refactor the context base to support more use cases
