Flugg with Geant4 9.5

Dear Users
The FLUGG interface (Fluka to geant4 Geometry)
works without modifications with the latest geant4 release
Geant4 9.5
Some caveats:

The embedded CLHEP classes - available in Geant4 9.5- are NOT used,
flugg users have to install the CLHEP package as before.

The "parallel layered mass geometry" feature is NOT supported in flugg

At present, the interface is available only at 32 bits with g77.

Please report any error/crash you may encounter.
Ciao
Paola
