// BrDbPlatformPosition is a class that maps onto the BRAHMS DB
// platform Position tables.  This table is expected to be change
// from run to run and will keep track of the angle of the various
// platforms (ie FFS, BFS, MRS).  The absolute positions of the
// various detectors will be calculated by using the detector tables
// (BrDbDetectorVolume, BrDbMagnetVolume) which store positions and angles
// relative to the platform and transforming to the absolute system using
// the information in these tables.
