// Class Description:
//
// An internal utility class, responsable for keeping parameters
// for low-energy EM and DNA physics processes and models.
//
// It is initialized by the master thread but can be updated 
// at any moment via G4EmParameters interface. It is not assumed
// to be used for a direct initialisation
