Dependence on Google for Geocoding

[jmealo]

There are open source Geocoding options available; however, they're not tolerant of typos. If we stick with PostGIS it has functionality to facilitate this.

My thinking is for typos in street names we can simply correct this by querying the street names.

I have JavaScript code that can roughly determine the different parts of addresses.

I'm thinking we can stick with Google for a while and perhaps log the queries temporarily and run them back with whatever solution we decide and compare the accuracy.
