	 * Modifications
	 *
	 * 6/4/2016
	 *
	 * had problems using jQuery JSON parsing
	 * used javascript JSON parse
	 * stringify to convert to a string - store in local storage
	 * get from local storage - JSON parse
	 *
	 * finally made markers appear in Google Maps
	 *
	 *
	 * 6/4/2016
	 * -loop through locations, getting their attribs and putting into markers
	 * -added infoWindow for markers, displaying HTML containing keyword count
	 * (and possibly some other useful data)
	 *
	 * TODO:
	 * -put keyword searched in the infoWindow
	 * (and data collected from Python scraper)
	 *
	 * -integrity of results.json file
	 *   correct json output from python->php->js
	 *   make sure it follows [{},{},{}]
	 *   include all results now (all areas)
	 *
	 *   PYTHON
	 *   -correct JSON output (or do it in PHP)
	 *   -might have to re run python scraper again
	 *   (note application of Google geolocation API keys )
	 *
