Monday tasks:

* new "well-foundedness" type property (like cardinality) specified in
  Theory kinds files; specifies well-foundedness and a ground term

* well-foundedness / finite checks in Datatypes now superseded by type
  system isFinite(), isWellFounded(), mkGroundTerm().

* new "RecursionBreaker" template class, a convenient class that keeps
  a "seen" trail without you having to pass it around (which is
  difficult in cases of mutual recursion) of the idea of passing
  around a "seen" trail
