  Have the GEM and TS enclosed volumes be slightly smaller than their mother volumes.

Make sure that the replicavol fills its mother volume exactly and completely by
increasing the size of each enclosing detector mother volume to 180 degrees.

  Leave a tiny gap between lead ring and virtual detector. Increasing the lead
ring will start overlapping with the virtual detector though, so watch out.

  Updates to lucite detector to avoid issues with voxels, with zero normal
vectors, with stuck photon tracks after 10 steps, with killed events
after 25 steps, etc...
* replicavol must completely fill its mother volumes
* there is now a glue layer implemented (material def from Qweak elastomer
  for quartz bars, most certainly not what we'll use for lucite)
* glue layer/lucite plane is now the unit that is replicated, which
  means there's a redundant layer of glue in the front
* lucite detectors can be tilted (default = 10 deg for demo), too large
  a tilt will result in overlap with TS layers. rotation is done as a
  whole, i.e. complete with lightguide and PMT.
* enclosing volumes are slightly larger than the daughter volumes to avoid
  identical faces (may not be an issue, but easier to tell the geometry
  in the graphical window this way)

Optical photons are now simulated fine. Remaining problem: they don't die!
Since the absorption length is set to 1000*m, they keep bouncing around
forever leading to minutes per event simulation time.

To get simulations that ignore optical photons (to first order), just disable
the Cerenkov process with
  /process/inactivate Cerenkov
