An API for using matcher-combinators outside the context of a test framework

Integration with clojure.test or cljs.test (depending on which platform
you're running on).

This namespace provides useful placeholder
vars for match?, match-with?, thrown-match? and match-roughly?;
the placeholders are nil (the actual implementations are extended
via the clojure.test/assert-expr multimethod), but importing these will prevent
linters from flagging otherwise undefined names.

Even if not concerned about linting, it is necessary to have
some namespace require matcher-combinators.test to ensure that
match? and friends can be used withing clojure.test/is.

Commonly, a dev-only user namespace will require this namespace.
