Updated spec for search_term to expect lat and lng fields. These are being required so that the search terms can be used to load the cache with whatever has been looked at before.
Added migration to allow for lat and lng to be captured for search_terms, in order to have search terms used to load the cache
Removed all references to zoning, as they are redundant
Adjusted model and controller to allow for lat and lng to be stored on the search term table
Updated map.js to pass lat and lng to the server.
Rake task to load the cache implemented. It can now be set up via the scheduler to make sure popular locations are ready to be served at all times.
