typed recursive constants in inductive and primrec definitions).

inconsistently typed in different primrec equations).

- Datatype package now also supports arbitrarily branching datatypes
(using function types).
- Added new simplification procedure for proving distinctness of
constructors.
- dtK is now a reference.
