// JCALL - AJAX CALL AND RESPONSE HANDLER
// @author : Jeremy Dill
// @ver : 1.6
// @param [str] func : php jCall function to execute
// @param [array] params : array of parameters ( "value1","value2" )  to be passed to the jCall function
// @param [obj/selector] opt : set of options for the ajax call.  Supported options include:
// 			[str] url : path to ajax.php, the entry point for ajax call
//			[bool] setWait (true) : if true, _PI.wait will be set to true before call, and will be set to false on response.  Global synchronous calling if you check _PI.wait before each request.
//			[string] mode - (assign) OPTIONAL FUNCTION CALL INSTEAD OF ASSIGNING NEW CONTENT TO TARGET, YOU CAN 'append','prepend,'after','before' OR 'replaceWith' ON THE TARGET SELECTOR
//			[bool] rapidFire (false) : if false, subsequent duplicate requests to the same func & params will be prevented and allowed only after response is completed.  Singular synchronous calling.
//			[bool] jsonly (false) : only return javascript...no xhtml, no target
//			[bool] scall (false) : pass session _PI.sess with request
//			[bool] layers (false) : pass _PI.layerid with request (current active layer)
//			[bool] noloader (false) : disable ajax loader (spinner)
//			[bool] persistLoader (false) :  keep loader (spinner) after returning response.
//			[int] timeBeforeGivingUp (10000): ms time to wait for response before giving up and throwing an error.
//			[func] timeoutAction (alert): function to run on timeout
//			[func] errorAction (alert): function to run on error
//			[func] precall (): function to run before ajax call.
//			[func] onSuccess (): function to run on on ajax success but before processing responses.  Return true to continue processing response or false to prevent futher processing.
//			[func] callback (): function to run on ajax success and after processing responses.
//			[func] onComplete (): final function to run on on ajax complete after all callbacks and response processing.
//			[obj] loaderOpts : set of options for loader.  Can clone loader object and reuse.
//				[int] delay (200) : ms time to wait after request before showing loader.
//				[int] transSpeed (10) : ms time for fadin and fadeout of loader.
//				[selector] sel ("#smallLoader") : ID selector for ajax loader graphic that gets placed next to target anchorpoint on page (don't use a class selector!)
//				[obj/selector] ap ("body") : specifies the object to place the loaderSel next to.  Optionally, use "where" to use the 'where' param[1] of servUp. Can also be a function returning a selector.
//				[str] loc ("top-right") : where to mount loader on ap.  options are based on placer plugin.	 Accepted presently: top-left, top-right, bottom-left, bottom-right, off-left, top-center
//				[obj] offset ({0,0}) :  x and y offsets for loaders.
// OPTIONALLY, opt can just be selector that then gets the apLoader treatment. This will use the default jcallLoader opts and build a 'spinner' next to the selector.
// @RESPONSE - JSON MULTI DIMENSIONAL ASSOC ARRAY, EACH DIMENSION MAY HAVE 4 PRIMARY KEYS :
//  'target' - A LOCAL JQUERY OBJECT "target" WHICH IS GOING TO GET THE RETURNED XHTML RESPONSE.
//			   TYPICALLY A SINGLE DIV OR BLOCK ELEMENT BUT CAN BE ANY ELEMENT OR JQUERY COLLECTION OF ELEMENTS (EVEN TABLE ROWS!)
//	'xhtml' - ANY HTML TO BE RENDERED TO EACH RESULT OF "target"
//	'js' - (REQUIRED) ANY JS TO BE EVAL AFTER XHMTL HAS BEEN RENEDERED.
// 	'linkJs' - ARRAY OF JS FILES TO BE LINKED TO THE PAGE (IF NOT ALREADY LINKED).
// 	'mode' - OPTIONAL FUNCTION CALL INSTEAD OF ASSIGNING NEW CONTENT TO TARGET, YOU CAN 'append','prepend,'after','before' OR 'replaceWith' ON THE TARGET SELECTOR
//  'kldr' - USE ALONG WITH 'persistLoader' OPTION TO CONTROL ON/OFF LOADER.  SET $resp['kldr']=1 IN FIRST RESPONSE TO KILL PERSISTANT LOADER
//
//  NOTE: FOR XHTML TO BE USED, YOU MUST RETURN THE 'target' JQUERY OBJECT.
//		 FOR EXAMPLE, IN PHP - $response['target']="target=jQuery("#mydiv");";
//		 IF NO TARGET IS INCLUDED IN THE RESPONSE, ONLY THE 'js' WILL EXECUTE.
//
// SET _PI.DEBUG=TRUE FOR DEBUG MESSAGES IN THE CONSOLE.
// SET OF DEFAULT OPTIONS FOR LOADER.  I RECOMMEND THAT YOU CUSTOMIZE THIS OBJ IN YOUR OWN SCRIPT. THEN FOR ALL CALLS, CLONE THE OBJECT, EXTEND THE CLONE, THEN PASS TO JCALL
