// Forward Multiplicity Detector based on Silicon wafers. This class
// contains the base procedures for the Forward Multiplicity detector
// Detector consists of 3 sub-detectors FMD1, FMD2, and FMD3, each of
// which has 1 or 2 rings of silicon sensors.
-//
// This class contains the detailed version of the FMD - that is, hits
// are produced during simulation.
