ML-Systems/smlnj-compiler.ML compatibility tweak;

include SVC_Test;

Theorems are only "pre-named" if the do not already have names.

Added function could_unify to speed up rewriting of proof terms.

Indexes of variables in expanded proofs are now incremented to avoid clashes.

moved SVC stuff to ex;

New function maxidx_of_proof.

New-style versions of these old examples

Rewrite procedure now works for both compact and full proof objects.

escape_mfix;

added literal;

prep_mixfix': proper use of Syntax.literal;

tuned;

mu-syntax for the LEAST operator

Multiset: added the translation Mult(A) => A-||>nat-{0} (which internalises the `multiset' relation). FoldSet: weakened the typing conditions of the function f and (by the way) removed the `locale' declarations.
