RichDigit doxygen

The RichDigit is a very simple class. It has no additional data members, the only information it stores is via the RichSmartID used as its key when saved into a container of RichSmartIDs.

This class is not created or stored during normal productions. For example, the RICH reconstruction works directly from RichSmartIDs decoded from the raw buffer, which are decoded into RichRecPixel objects which are non persistent data objects used only during the RICH reconstruction.
