- Working on #75, at least got the plotting working again.  Not sure if this is being done correctly yet or not though.  Also, need to go through carefully and check all imports for all functions inside specutils/ that they are importing everything they might need correctly, including Error classes.  Also need to check that each python module can be imported by itself and run, that the various ./test scripts run, and that I can import make_hst_spec_previews and run it from another python script.  Also that I can:
 import utils.specutils.edge_trim instead of having to say import utils.specutils.edge_trim.edge_trim (I think this is the test)...
If so then I think victory can be claimed.
