adding examples for the potential counterexamples in the simple scheme

also potential counterexamples in the simple exhaustive testing in quickcheck

quickcheck does not show evaluation terms of equations if they are simply free variables to avoid duplicated output; tuned

adding more verbose messages to exhaustive quickcheck

quickcheck narrowing also shows potential counterexamples

adding a exception-safe term reification step in quickcheck; adding examples

quickcheck returns counterexamples that are potentially spurious due to underspecified code equations and match exceptions
