Auto generated docs from examples

[Resseguie]

Should we copy over the mechanism for auto-generating docs from examples as used in Johnny-Five?

The ones I added so far were manually copied and edited because I wasn't aware of the J5 auto-generated method at the time.

Ugh, I hate the code used there, but if you want to do that then sure :\

I'm open to alternatives. Or I'm okay with doing them manually for now if you'd rather keep it simple.

If you want to copy the grunt task, go for it
