/**
   \class MollerGlobalMagnetField
    
   \brief Set in MollerDetectorConstruction as the field manager.

 MollerGlobalMagnetField::MollerGlobalMagnetField() sets the field map names, initializes 
 the grid after setting the min and max r, z, phi, and reads in the maps.  
 MollerGlobalMagnetField::GetFieldValue() adds the field value for the hybrid and upstream toroids 
 from MollerMagnetFieldMap::GetFieldValue (which does the interpolation) during tracking.
