netCDF file loading function

This function adds the ability to load netCDF files into python for further analysis using our analysis library. Metadata gets stored in a dictionary and image data is made available as a numpy array.
ok.  To me `NxNxN` reads as 'a cubic array with N entries in each direction'.  I would go with `MxNxP` (or some other third letter) or (z, y, x) giving the order of the dimensions.
