// 2004-02-02 - Set theStatus = Undefined at start of DoIt
// 2005-07-28 - add G4ProcessType to constructor
// 2006-11-04 - add capability of calculating the reflectivity
// off a metal surface by way of a complex index
// of refraction - Thanks to Sehwook Lee and John
// Hauptman (Dept. of Physics - Iowa State Univ.)
