Last change on this file since 40c5104 was 7a04dbb, checked in by krzywon, 10 years ago

Removed the last vestiges of the SANS references and ran run.py. Tested
loading multiple file types and ran fits, p(r) and inversion. Help
windows loaded properly. Saving and loading projects and analyses acted
the same as before the conversion.

All unit tests run by utest_sasview.py passed.
