GET crops/seeds/members by coordinates/location input

[sbutler-gh]

I would love to be able to send an API request like

/api/v1/crops/{lat: X, lon: Y} /api/v1/seeds/{lat: X, lon: Y}

And return the crops/seeds being grown close to that specific location. I'm new to API development, so I'd be glad to contribute on something like this as well, and learn along the way.
