Moves to new JOINT Input and Joint measurement card format. Adds GiBUU multi-species flux component scaling. NOTE: Some small signal def changes here.

Changes:

• scripts/nuiscardgen:
  • No longer need GiBUU_nu and GiBUU_nub Input types.

• src/FCN/JointFCN.cxx:
  • Receives re-indent.

• src/FCN/SampleList.cxx:
  • Adds MiniBooNE_CCQE_CTarg_XSec_1DQ2_antinu

• src/FitBase/CMakeLists.txt`;
  • Adds InputUtils to build.

• src/FitBase/EventManager.cxx:
  • Receives re-indent.
  • Input ID getting is now less dependent ons tring comparisons.
  • The caller is now responsible for determining the input type when instantiating a new InputHandler.

• src/FitBase/InputHandler.cxx:
  • Receives re-indent.
  • Updates to allow either old: "TYPE:file1.root;TYPE:file2.root", or new "TYPE:file1.root;file2.root" format for Joint measurements.
  • Input type is now an enum and uses the InputUtils namespace.
  • Updates to GiBUU handler for determining dominant flux species and flux species component weights from the input file
    • GiBUU no longer needs to have two input types.

• src/FitBase/MeasurementBase.cxx:
  • Receives re-indent
  • Uses new InputType format for interface with event manager and input handlers.
  • GiBUU flux species weights are applied for measurements identifying themselves as including wrong sign background contributions.

• src/FitBase/StdHepEvt.cxx:
  • Adds new input branches for species weights.

• src/MINERvA/MINERvA_SignalDef.cxx:
  • Now uses PhysConst namespace for charged pion pdg array.

• src/MiniBooNE/MiniBooNE_CCQE_XSec_1DQ2_antinu.cxx:
  • Adds possibility to use corrected carbon target data.
  • Self identifies as a 'kNumuWithWrongSignMeasurement'.
  • Now uses PhysConst to check for either muon species.

• src/MiniBooNE/MiniBooNE_CCQE_XSec_1DQ2_nu.cxx:
  • Self identifies as a 'kNumuWithWrongSignMeasurement'.
  • Now uses PhysConst to check for either muon species.

• src/Routines/ComparisonRoutines.cxx:
  • Receives re-indent.
  • Adds checks for mis-ordering of input card file sample lines, common problem where 'FIX' is included at the position expected of in the input file.

• src/Utils/SignalDef.h:
  • Fix for moronic bug in isCCWithFS (thanks for spotting this Clarence.)

New Files:

• src/FitBase/InputUtils.{c,h}xx:
  • Some parsing utils and enums used when handling input lines in card files.
