Validation lib

[g-a-v-i-n]

I wrote a general purpose object validator module called obcheck. I used this branch to prototype it. Now it has been moved it to it's own repo, so the prototype is completely gone and the NPM package is implemented in it's stead. This also includes nomenclature changes to be less music-player-y and more are.na-app-y.

• [x] write package
• [ ] ensure branch stability
• [ ] ensure obcheck stability
