/* Heavily modified exact_autocomplete functionality by Exact */
/* Version 0.5.6 @ 12.03.2008 */

/* 
	Usage and available attributes (all optional):

	$("#text_input").superinput({
		suggestURL: 'search2.php',	// PHP file to ask suggestions from
		suggestMethod: 'GET',		// method (POST/GET) used to send search string if suggestURL is used. Default is GET
		canAdd: true,				// whether new values can be added or not if suggestURL is used. If suggestURL is not specified, this defaults to TRUE. 
		validateFunction: val,		// JS function that checks if new value is valid (returns TRUE or FALSE). Has one argument (new value inserted)
		limit: 5,					// Limits the number of items that can be added
		cellSeparator: '///',		// Separator to use with the text field 
		value: "alias4///alias5",	// Default value to use with the input field
		minChars: 3					// Minimum number of characters to start auto-suggest with. Defaults to 3
		onItemSelect: myCallback	// Callback function. Called when user selects item from suggested autocomplete list (one parameter is passed {selectedItem:{id:X, text:Y}, selectedItems:array})
		postExisting: true			// Posts item ids already existing in superinput, $_POST['existing'] = array(0 => 43, 1 => 4, 2 => 5). Default is false
		cacheLength: 0				// 0 - means no suggested results are cached and each time suggested items are requested. Default: 1
	});
