34// Description: Contains material properties for optical materials. These
35// may be used in a user application instead of defining one's own. In user
36// code, write for example:
37// G4MaterialPropertiesTable* mpt = new G4MaterialPropertiesTable();
38// mpt->AddProperty(keyname, materialname);
39// where keyname is the key (e.g. "RINDEX") and materialname is the
40// name of the material (e.g. "Air")
41// The vectors are to be in order of increasing energy (as required by
42// G4PhysicsVector. If wavelength is specified rather than energy,
43// specify it in decreasing value and call ConvertToEnergy().
