MatcherClass support for complex matching

[grosmar]

Hi,

I've extended your Matcher enum with a new type: matcherClass

This way you can provide classes instead of just functions.

Also created a MatcherClass typedef for it, so the system is independent from any concrete implementation.

I did it to use hamcrest for argument checking, this way i call use all the crazy hamcrest Matchers for checking the conditions.

The usage is pretty simple after:
someMock.someFunction(cast matcherClass(endsWith("Bar")));

And as an addition I've removed the warning, if there is no munit defined, because it works with any test runner that is based on annotations. (like hexUnit https://github.com/DoclerLabs/hexUnit).

I want to modify later the macro to be able to receive configuration for the annotation and field names from outside.

I hope you like the modification.

Cheers,
