Tests for Matchers

[adaamko]

I think it would be great if there were test cases for matchers now as we begin to support lot of things now. In the test folder there are some tests now for rules, we could add more there, especially when we introduce new mechanisms.

Thoughts?

Also some small sample rules/sentences for our use-cases (e.g. BRISE, Hatespeech). Especially since we want to introduce a new Graph class and these tests would make the conversion much easier.

Love both ideas!
