Find tool to discover coordinates for tester addresses

[smarziano]

Relates to #63

This tool will be connected to Patterns. Therefore, CUTGroup tester signs up and address info is sent to Patterns. Patterns then sends address info to tool, and receives coordinates which is then fed back into Patterns.

One of things we need to determine is what services have Terms of Use that allow what we want to do in terms of saving geocoding results in the Patterns database.

Some options:

• Google Maps Geocoder
• Mapbox Geocoder
• Others?

Mapzen Search https://mapzen.com/products/search/

Mapzen Search is built on their open source Pelias geocoder (https://github.com/pelias/pelias) so an organization could set up their own Pelias search instance if desired instead of using Mapzen Search. Both Pelias and Mapzen Search versions are supported in the geocoder gem (https://github.com/alexreisner/geocoder#mapzen-mapzen)
