Merged requested to merge RichKernelSplitUp into master
Adapts to the changes in LHCb!239 (merged)
Also, splits RichRecBase into 4 smaller packages
RichRecUtils - Small utilities. RichRecEvent - The XML based transient event model used in the RICH Reco. RichRecInterfaces - Tool interfaces RichRecBase - tool and algorithm base classes.
Of these, probably only RichRecUtils will be used by the upgrade framework. The others need extensive changes.
