Edit make-cal to have option to use MetadataFactory
Added additional options and functionality so that make_cal can use WebAbsolutes OR MetadataFactory.
I have tested this and it works. Some things to consider:
- Maybe I should add the same options from make_cal.py to magproc.py
- Perhaps the WebAbsolutes option should be removed entirely once the old database is shutdown
- Should we have a separate method to convert Metadata class to Readings class?
