2005-04-21 berghofe 2005-04-21 - Eliminated nodup_vars check. - Unification and matching functions now check types of term variables / sorts of type variables when applying a substitution. - Thm.instantiate now takes (ctyp * ctyp) list instead of (indexname * ctyp) list as argument, to allow for proper instantiation of theorems containing type variables with same name but different sorts.
