Add a note about array Types to Provider

Unfortunately this changes the intention of those fields, @sethherr. These are meant to be arrays, e.g. a vehicle may have more than one propulsion_type. See the related discussion on #48.

Ahh. That's an important distinction, that Type declaration wasn't clear to me.

[thekaveman]

Indeed there is room for ambiguity. See our discussion on #46 and #53, where we are exploring JSON-Schema to more clearly define the spec in a machine-readable/machine-verifiable format.

I put a note about it being an array in the description, I think this would have clarified it for me?

I think JSON-Schema could be great, this is more of a quick fix...

[thekaveman]

Nice clarification!
