Skeleton PathAssert, plus tests -- NOT FOR INCLUSION. Yet.

Skeleton based on existing code. I modeled it on FileAssert. In fact I saw nothing related to anything java.nio.file in the code, so I created it from scratch...

Preview only. I know the coding style does not fit; knowing that I use IDEA, do you happen to have a style file available?

Also, about error messages: there seem to be a lot of factories; FileAssert seems to basically use one per message! Is that on purpose? Can I create a single factory for Path-specific operations (including exists, non exists and absolute)?

Please comment! I'll add more test when the base is good enough for you.
