I don't like it.  It seems to me that it embeds the assumptions the CM
makes even deeper.  And I want to remove some of those assumptions.

These assumptions include:

- Workers may only produce primary stats.
- Specialists may only produce secondary stats.
- Specialists may only produce _one type_ of secondary stat.

I certainly want to remove the third assumption; this is needed for an
SMAC-like compatability mode.  I hope to remove the second assumption;
this is needed for a MoM or MoO-like compatability mode.  I'm not sure
about the first assumption but I suspect that if the second and third go
it will be of little use.
