- Moved rewriting functions to meta_simplifier.ML
- dest_abs now also takes an optional variable name as an argument
- beta_conversion takes additional flag as an argument. Fully reduces
the term if set to true
Some tuning:
- tuned fix_shyps in instantiate, implies_intr, implies_elim, reflexive,
transitive, beta_conversion, abstract_rule
- combination: chktypes derives types of f and t from type of == instead
of using fastype_of
New primitives:
- eta_conversion
- incr_indexes: increment indexes in theorems
- cterm_incr_indexes: increment indexes in cterms
- cterm_match, cterm_first_order_match
- rename_boundvars
