Wrap CSCConditions class for use in CSC local reconstruction, in analogy with wrapper classes Rick uses in CSCDigitizer.
CSCConditions encapsulates the conditions data (e.g. calibration data) from the database and presents it as CSCRecHitD requires (and that is somewhat historical!)
All functions in public interface accept CSCDetId for ME1A (i.e. ring 4) with channel number 1-16 (and not the raw ME11 channel 65-80).
