/**
* Binds geocoding functionality to the model specified.
*
* @param string $class A fully-namespaced class reference to a model class that `Geocoder`
* should bind to. Assigns configuration for the model, and attaches custom
* behavior to perform geocode lookups and location-based searches.
* @param array $config An array of configuration settings defining how `Geocoder` should
* behave with this model. The available settings are as follows:
* - `'service'` _string_: The name of the API service to use when geocoding
* addresses. You can configure custom lookup services, but by default, the
* available options are `'google'` or `'yahoo'`. Attempting to use an undefined
* service will result in an exception.
