[incomplete] starting a definitions idea

Due to my desire to not have to manhandle every misstep in the MD spec I went ahead and traded one format for another, mostly because it's formated like data. Included is a little code to take a yaml doc and parse it to a useful and we can abstract this to other aspects like the abbrv docs and anything else that is really just a list of dt/dd links (or with some minor template tweaks anything else). 

NOTE: currently I have not impliemented a custom syntax for how to do interpage links (ie see [other term]) as it seems out of band and very janky.

Ideally all of this ~SHOULD~ be replaced by jekyll when gh-pages is setup though it sounds like there is more planning that needs to go in to making that investment.
