Improved the error messages when a Spec fails.

The function explainSpec no longer drops explanations on TypeSpec
Added guardTypeSpec, which catches errors earlier, so there is less noise.
function symbols like subset_ and member_ print a elided version of their set
arguments when they are large literals. Improves readabilty as irrelevant
information no longer overwhelms the user.
Add the constructor ExplainSpec to Specification
Assert now has type Assert :: Term fn Bool -> Pred fn
