+// 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.
