Added Mathematica package to import BOUT++ data. To use:

 - Add 'AppendTo[$Path,"<full_path_to_BOUT>/tools/mathematicalib"]' to /home/jto500/.Mathematica/Kernel/init.m
 - Call 'Import["BoutCollect.m"]' in Mathematica

Then you can use e.g. 'f=BoutCollect[variable,path->"data"]' or 'f=BoutCollect[variable,path->"data"]'. 'bc' is a shorthand for 'BoutCollect\. All options supported by the Python collect() function are included, though Info does nothing yet.
