CIT_magic can now import from a different file than the working directory.  this commit also reverts Nick's commit: 51df87104b83b664e03237b2a8ca0f705410fbcb, which had broken CIT_magic with the existing datafiles
converting 2gbin functionality to take a directory instead of a single file.  not done
2g-bin basically working as expected, but still trying to track down a small inconsistency between performance in MagIC.py and QuickMagIC.py
2g-bin magic is up to code
Merge branch 'MagIC_beta'
