Added coord.py and zscale.py as stand-alone scripts in support. Started removing astLib.
Removed some references to astLib and verified that the new set up works.
Removed old references from DistanceObject.py
Removed extraneous requirements from some more files.
Removed unnecessary reproject_map file (external package removal was not easy)
