"0" means display Sunday first, "1" means display Monday first, etc. *   align         | alignment (default: "Br"); if you don't know what's this see the calendar documentation *   range         | array with 2 elements.  Default: [1900.0, 2999.12] -- the range of years available *   weekNumbers   | (true/false) if it's true (default) the calendar will display week numbers *   flat          | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID *   flatCallback  | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar) *   disableFunc   | function that receives a JS Date object and should return true if that date has to be disabled in the calendar *   onSelect      | function that gets called when a date is selected.  You don't _have_ to supply this (the default is generally okay) *   onClose       | function that gets called when the calendar is closed.  [default] *   onUpdate      | function that gets called after the date is updated in the input field.  Receives a reference to the calendar. *   date          | the date that the calendar will be initially displayed to *   showsTime     | default: false; if true the calendar will include a time selector *   timeFormat    | the time format; can be "12" or "24", default is "12" *   electric      | if true (default) then given fields/date areas are updated for each move; otherwise they're updated only on close *   sortOrder	   | ("asc"(ending)/"desc"(ending)/"none"). If "asc" (default), order of the multiple dates (when multiple dates is on) will be sorted in ascending order. Otherwise, it will be sorted in descending order. "none" means no sorting is needed. *   step          | configures the step of the years in drop-down boxes; default: 2 *   position      | configures the calendar absolute position; default: null *   cache         | if "true" (but default: "false") it will reuse the same calendar object, where possible *   showOthers    | if "true" (but default: "false") it will show days from other months too *   saveDate      | if set (default unset) will save a cookie for this duration. *   numberMonths  | Have the calendar display multiple months *   controlMonth  | When displaying multiple months, this will be the control month. Default 1. *   vertical      | When displaying multiple months, months can progress in a vertical or horizontal way. Horizontal is the default. *   monthsInRow   | When displaying multiple months how many months in a horizontal row. Works both in vertical and horizontal mode. Default numberMonths *   fdowClick     | Allow click on Days of Week 1st day *   titleHtml     | Html you can put in title of calendar *   noHelp        | Disables "?" button in your calendar *   noCloseButton | Disables "X" button in your calendar *   disableYearNav| Disables year navigation buttons *    * \endcode * *  None of them is required, they all have default values.  However, if you *  pass none of "inputField", "displayArea" or "button" you'll get a warning *  saying "nothing to setup". */Zapatec.Calendar.setup = function (params) {	paramsList = ["id"];	function param_default(pname, def) { 		if (typeof params[pname] == "undefined") { 			params[pname] = def; 		} 		paramsList.push(pname);	};	params.id = Zapatec.Utils.generateID("calendar");	param_default("inputField",     null);	param_default("displayArea",    null);	param_default("button",         null);	param_default("eventName",      "click");	param_default("closeEventName", null);	param_default("ifFormat",       "%Y/%m/%d");	param_default("daFormat",       "%Y/%m/%d");	param_default("singleClick",    true);	param_default("disableFunc",    null);	param_default("dateStatusFunc", params["disableFunc"]);	// takes precedence if both are defined	param_default("dateText",       null);	param_default("firstDay",       null);	param_default("align",          "Br");	param_default("range",          [1900, 2999]);	param_default("weekNumbers",    true);	param_default("flat",           null);	param_default("flatCallback",   null);	param_default("onSelect",       null);	param_default("onClose",        null);	param_default("onUpdate",       null);	param_default("date",           null);	param_default("showsTime",      false);	param_default("sortOrder",      "asc");	param_default("timeFormat",     "24");	param_default("timeInterval",   null);	param_default("electric",       true);	param_default("step",           2);	param_default("position",       null);	param_default("cache",          false);	param_default("showOthers",     false);	param_default("multiple",       null);	param_default("saveDate",       null);	param_default("fdowClick",      false);	param_default("titleHtml",      null);	param_default("noHelp",         false);	param_default("noCloseButton",  false);	param_default("disableYearNav", false);	param_default("disableFdowChange", false);	if (params.weekNumbers) {		params.disableFdowChange = true;		params.firstDay = 1;	}	param_default("disableDrag", false);	param_default("numberMonths",   1);	if ((params.numberMonths > 12) || (params.numberMonths < 1)) {		params.numberMonths = 1;	}	if (params.numberMonths > 1) {		params.showOthers = false;	}	params.numberMonths = parseInt(params.numberMonths, 10);	param_default("controlMonth",   1);	if ((params.controlMonth > params.numberMonths) || (params.controlMonth < 1)) {		params.controlMonth = 1;	}	params.controlMonth = parseInt(params.controlMonth, 10);	param_default("vertical",       false);	if (params.monthsInRow > params.numberMonths) {		params.monthsInRow = params.numberMonths;	}	param_default("monthsInRow",    params.numberMonths);	params.monthsInRow = parseInt(params.monthsInRow, 10);	param_default("multiple",       false);	if (params.multiple) {		params.singleClick = false;	}	param_default("canType",   false);		var tmp = ["inputField", "displayArea", "button"];	for (var i in tmp) {		if (typeof params[tmp[i]] == "string") {			params[tmp[i]] = document.getElementById(params[tmp[i]]);		}	}	if (!params.inputField) {		params.canType = false;	} else {		params.inputField.setAttribute("autocomplete", "off");	}	if (!(params.flat || params.multiple || params.inputField || params.displayArea || params.button)) {		alert("Calendar.setup '" + params.id + "':\n  Nothing to setup (no fields found).
