// AliESDFMD is the Event Summary Data entry for the FMD.  It contains
// a rough estimate of the charged particle multiplicity in each strip
// of the FMD.    It also contains the psuedo-rapidity of each strip.
// This is important, as it varies from event to event, due to a
// finite interaction point probability distribution.
