Package JavaDoc to clarify what this artifact is & does

Full disclosure: I LIKE the concept of what one could call
MockitoNotImplementedExceptionAnswer, and have separately implemented
the same (one can find this idea publicly on the web in several places).

I don't think having this configured by default automagically is good;
that is just too sneaky and surprising IMHO.  One should be able to use
a popular utility and expect it to behave as it's documented?

No offense meant to anyone.  None taken I hope.
