Analysis macros from Ronald that illustrate his PID method

- PID probability calculation using the Bayesian method
- This includes code that he used to generate the efficiency maps as a
  function of true momentum and lab theta angle of tracks
Fix bug in CM theta and cos theta calculation

- The angles should be calculated wrt. lab z and not wrt boost vector
Macros for Dec14 PCM talk

- Macro used to produce figures for PCM talk
- Fill some t vs angle distributions in fill.cpp
- Macros to run analysis modules (tbc next round)
- x-section data for pbarp->pi0pi+pi-
- Event counting macro in simulation files
Analysis module changes

- Use initializer lists (weird bug with uninitialized RhoCandList
  objects otherwise)
- Simplify the truth matching functions now that the BG MC has full
  ancestory info
- Fill the efficiency hists only if there is anambigous full truth match
- Update some histogram range definitions and pi0 selection cuts that are
  beam energy dependent
- Brem correction option is constructor argument
Modifs to simplified analysis module

- Use initializer lists for all members
- Some new histograms for t/u binned mass hists
- Eid checks for Sig and truth match for BG
- Calculation of true t/u for events
- Some experiments on how to fill candidate list for charged tracks
- t/u reconstruction resolution dists
