Add address geocoding support to API #7
Description
Allow USPS addresses to be used as input to the API via the location parameter:
/nearest/{count}/{sourceType}/to/{location}[/within/{distance}/{units}]
This will require live support for Geocodio's API. Other Address-to-LL APIs worth looking at are PositionStack and Geocodeapi.

The data import script could feasibly be updated to include geocoding using the same service.
