Custom matcher tutorial

I wrote some quick notes up on a custom matcher I wrote around a
pattern that I am using constantly.

You could use it as a custom matcher tutorial for the uninitiated or
as a possible solution for validations specs for the more advanced.
Or you could use it to school me, and explain why my code sucks :slight_smile:
