Define API and modify backend code to return values in that way for FindNearby

I think FindNearby could be done like this:

Input parameters

• email (assuming that will be user unique identifier)
• long
• lat
• radius/distance away
  ** do not return anything greater than the radius

Return value would be JSON list (string) of targets sorted by distance away from lat/long. Sample:

{
{ 'name': 'David', 'email': 'x@e.com', 'distance': '10'},
{ 'name': 'Jeremiah', 'email': 'y@e.com', 'distance': '15'}
}
