Provide code for lossless conversion from genie::EventRecord to/from simb::MCTruth
In order to preserve the necessary info for GENIE event re-weighting, but not tie the code base to linking to GENIE dictionaries we need a lossless conversion between the two classes. MCTruth gets stored in the ART record, but can be converted back to genie::EventRecord in order to calculate new weights.

Code to do this was provided by Nate Mayer as
GTruth. Currently one small outstanding issue is:
RetrieveGHEP(simb::MCTruth,simb::GTruth) is not correctly setting KinePhaseSpace_t in SetDiffXSec() At the time of the conversion to R-2_8_0 (2013-05-01) this is not critical But it should be fixed
The necessary interface for getting the parameter from the GENIE GHEP record was added to R-2_9_0. Needs to be called by
nutools code and stored in the
GTruth record, and restored upon recreation.
