// Class Description:
// G4Mesh encapsulates and validates a nested parameterisation, which we
// call a "mesh". If a valid mesh cannot be created out of this
// G4VPhysicalVolume* (which will probably be most common), it will
// have a type "invalid". Then, usually, it may simply be destroyed.
// The overhead of an invalid attempt is expected to be small.
