+// Forward Multiplicity Detector based on Silicon wafers. This class

+// Detector consists of 3 sub-detectors FMD1, FMD2, and FMD3, each of

+//
+// This is the base class for all FMD manager classes.

+// The actual code is done by various separate classes. Below is

+// * AliFMDSimulator
+// This is the base class for the FMD simulation tasks. The
+// simulator tasks are responsible to implment the geoemtry, and
