Detailed Description

Encapsulates a user interface into the CSC conditions

Author

Rick Wilkinson

Tim Cox

Interfaces generally use "channels" which count from 1 and are 'geometric' i.e. in the order matching local coordinates. This is the channel labelling in CSCStripDigi (and CSCWireDigi) after internal corrections within CSCRawToDigi.

The input CSCDetId is also 'geometric channel level' i.e. ME11A has its own CSCDetId even in the ganged case,

Ganged ME1a channels are 1-16 (and unganged, of course, 1-48)

From CMSSW 61X, this class also handles separate algorithm versions for indexing the conditions data and for mapping between online and offline channel labelling.
