added calibration and polarization matrices
working pickle save and load. plot examples
separate calculation and save functions
integrating with some hall stuff that is already implemented in vme_analyze.py
Nonfunctional attempt to use python to edit IDL files

Python doesn't write to binary in the same way that IDL does.
I attempted to correct the magnetic data and redo it in a way that
is compatible with both IDL and Python.

But this isn't a good use of my time.  So I'm going to just make reduced
hall data and store that instead.
optimized read routine by using numpy.from file instead of magnus approach
numpy output is np.float32 which matches IDL output
minor updates
