I compiled g3tog4 with STL and try to convert our G3 RZ file to G4 geometry
using g4geom.cc. When the program was started, it was aborted at that the jump
of the id number (1st argument of these function).
ex.)
G4gstmed( imate=1,...);
G4gstmed( imate=2,...);
G4gstmed( imate=4,...); <-- aborted. (same for G4gsrotm)

For G4gsrotm, that id has to start with 0. In our RZ file it started with "1",
and that killed the program. When I add dummy with "0", it seems solbed problem
tempolary.

Is that the problem of our geometry or of g3tog4?
