Focus on User's Location on First View

[mattkendall]

Older versions of the site focused in on sites "near" the current location. Much of the bones are still in place and just need to be connected together.

There is a service available in services.js that will return a JSON structure with an overview of the map data, including a bounds object that surrounds all properties within 1 mile. The structure looks something like this:

{
  "dates": ["2015-02-05"], 
  "towns": ["Cary"], 
  "closest": {
    "bounds": [-78.9149484920922, 35.8291827138123, -78.8841665382659, 35.8632290159], 
    "permits": []
  }, 
  "categories": ["rezone", "subplan"]
}

The bounds object needs to be pulled from the service and then fed into the maps object in the gmap.js service. There's an example of manipulating the bounds here: https://github.com/mattkendall/cfa-cary-django-site/blob/pivot-data/permit_map/static/permit_map/js/map-directives.js
