// Twitter Bootstrap Typeahead doesn't support remote data querying. This is an expected feature in the future. In the meantime, others have submitted patches to the core bootstrap component that allow it. 
// The following will allow remote autocompletes *without* modifying any officially released core code. 
// If others find ways to improve this, please share.

    var autocomplete = $('#searchinput').typeahead()
        .on('keyup', function(ev){

            ev.stopPropagation();

This is a fork of Bootstrap Typeahead that adds minimal but powerful extensions.

For example, process typeahead list asynchronously and return objects

  # This example does an AJAX lookup and is in CoffeeScript
  $('.typeahead').typeahead(
    # source can be a function
    source: (typeahead, query) ->
 # this function receives the typeahead object and the query string

/**
 * Generates the string for the Haversine function. We assume that the `zipcode`, `latitude`,
 * and `longitude` columns are named accordingly. We are also not doing much error-checking
 * here; this is a simple text cruncher to make things prettier.
 * We may also be integrating some extra SQL in, passed in via the $extra parameter
 * 
 * @param   string      $table      The table to search in
 * @param   float       $lat        The latitude part of the reference coordinates
 * @param   float       $lng        The longitude part of the reference coordinates
 * @param   int         $radius     The radius to search within
