<Comment> You will notice several instances of a structure that looks like:

                    (age.coalClusters + age.coalVeins + age.coalClouds +
                        age.coalHugeVeins + age.coalSmallClouds +
                        age.coalVikingPipes + age.coalJRoushPipes +
                        age.coalNone)>0,

          The idea here is simple. The first, and last, line are
          "standard". They never need to be edited. The middle line
          contains all local distributions, separated by plus's.
          It may be empty if you have no local distributions.

          Other than defining new symbols on a single line, and
          adding them to these constructs, no other editing should
          be needed.

          Gaah, so it turns out that there will be a need to specify
          distributions for the "random choice" case. Frumble ...
