Can we get better docs for arg verification functions please?

Looking at the source I can see we have functions such as deepEqual notNull, objectContaining which seem nice and are well named but aren't documented anywhere. Can you please document these and also document if custom verifications exist.

So looks like people can make their own matchers if they want if they make a class that extends Matcher. https://github.com/NagRock/ts-mockito/blob/master/src/matcher/type/Matcher.ts

Also just want to say this is a nicely written lib. Were you guys inspired by go and its standard naming and folder layouts?
