[Gate-users] Adding material LYSO to Materials.xml

[Alex Vergara Gil]

AFAIK LYSO is a crystal like material, so it is already used in the
crystalSD detector, please correct me if I am wrong. So it is better
used that way because Geant4 can simulate all kind of crystalline
effects and it will be more realistic approach.

Alex
