//	SERVER-SIDE MODULE
//	(PLEASE DO NOT MODIFY THIS CODE)
//
//	The JS proxy to the Free The Air Web Service (FTA_WS).
//
//	It exposes a set of verbs each which correspond to their server-side
//	equivalent. Some verbs include:
//
//	searchStore ().
//
//	USAGE:
//	Pass the constructor an application-level object, whose callback functions
//	will be invoked to accept any responses from the web service.
//	The name of these callback functions are identical to the name of the
//	verb.
//
//	For example, consider SEARCH_STORE.
//
//	Your application code would look as follows:
//	var	fta_ws = new FTA_WS (myAppObject);
//	fta_ws.searchStore (...);		<<- sends the SEARCH_STORE request
//	myAppObject.searchStore (...)	<<- receives the SEARCH_STORE response
//
//	The interface is designed to be comfortable to a JS application developer
//	and is shielded from the low-level wire-protocol implementation mucky details.
