 What's:
	 php code for testing jsonp and ajax features
	 
	 receive get parameters:

 		search.php?q=dark
 	response:
		[{"loc":[41.34419,13.242145],"title":"darkblue"},{"loc":[41.67919,13.122145],"title":"darkred"}]

 Example Jsonp:
 	request:
 		search.php?q=dark&callback=L.Control.Search.callJsonp
 	response:
		L.Control.Search.callJsonp([{"loc":[41.34419,13.242145],"title":"darkblue"},{"loc":[41.67919,13.122145],"title":"darkred"}])

 Example Bulk data:
 	request:
 		search.php?q=roma&cities=1
 	response:
		[{"title":"Romainville","loc":[48.8854,2.43482]},{"title":"Roma","loc":[41.89474,12.4839]},{"title":"Roman","loc":[46.91667,26.91667]}]


 Example Ajax Empty Result:
 	request:
 		search.php?q=xx
 	response:
		{"ok":1,"results":[]}

 Example Error Result:
 	request:
 		search.php?s=dark
 	response:
		{"ok":0,"errmsg":"specify query parameter"}
