Merged requested to merge RichRecModernize into master
Miscellaneous C++11 updates to the RICH reconstruction.
Converts a number of properties previously using STL vectors to fixed sized STL arrays. Better type (size) safety and a small performance improvement.
Adds a common base class for all photon predictors in RichRecPhotonTools.
Adds some more virtual specifiers (might cause some warnings with clang if I missed some...)
