Many routines in this package are written to take advantage of known structure on some posets to quickly precompute some of the cached data. However, this may not always be desirable, and so this flag toggles whether precomputation occurs. It can be set with the setPrecompute method.
As an example, chain posets are known to be distributive lattices. If the precomputation flag is set, then the method fills this in automatically.

We also know that the dual of a distributive lattice is again a distributive lattice. Other information is copied when possible.
