Alternate "real_sno" detector configuration using the CAD model of the

acrylic vessel.  There are serious issues with this model which
probably make it unsuitable for photon propagation at the moment.

(Example: Why do you need to traverse 8 surfaces to cross the acrylic
vessel?  There should only be 4.)
