*
* Goptimize - do any Geant3 geometry/tracking optimizations
*
* The actual definitions of the materials, tracking media and volume
* tree are found in the file hddsGeant3.f which is generated automatically
* from the HDDS xml geometry database by the translator hdds-geant.
*
* NOTE: It is tempting to put Geant geometry and tracking optimization
*	commands into hddsGeant3.f at the point where the geometry is
*	being defined.  DO NOT DO THAT.  Put them here in this file.
*
* This routine is part of the HDGeant simulation package

c     User optimizations go here
c     such as: gsnext, gunear, gsord,
