Fixed issues with assertions about ftype and rad. Code is now more general and allows for remote and local fetching of .map or .mapex files. Also updated documentation and implemented __name__==__main__ testing.
Updated some more documentation, removed unnecessary code regarding fnamefmt.
Changed fetchUtils methods to be even more general. Removed rad, ftype, and channel arguments. Replaced them with remotedict and localdict. Also updated documentation.
Merge branch 'develop' of github.com:vtsuperdarn/davitpy into develop
