WCSim has frequent run-time exceptions similar to the following

-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : GeomNav1002
      issued by : G4Navigator::ComputeStep()
Track stuck or not moving.
          Track stuck, not moving for 10 steps
          in volume -WCBarrelCell- at point (3959.9,-3702.27,2.34479e-13) (local point (3957.38,-141.338,100.509))
          direction: (-0.778292,0.362641,-0.512595) (local direction: (-0.796092,-0.484489,-0.362641)).
          Potential geometry or navigation problem !
          Trying pushing it of 1e-07 mm ...Potential overlap in geometry!

*** This is just a warning message. ***
-------- WWWW -------- G4Exception-END --------- WWWW -------

Investigate whether these exceptions indicate fixable flaws in the geometry construction, or if they can be abrogated in some way.

The suggestion of overlaps indicates that it may be related to https://github.com/spradlin/WCSim/issues/24.
