// Class G4VCellScorer
//
// Class description:
//
// This is an interface for an object which does scoring for one cell
// of a geometry.
// The cell may be a physical volume or replica in the mass or a 
// parallel geometry.
//  
// Three different situation of the step with respect to the cell
// are separated: entering end exiting the cell and stepping inside
// the cell.
