/**
* Calendar is the base class for the Calendar widget. In its most basic
* implementation, it has the ability to render a calendar widget on the page
* that can be manipulated to select a single date, move back and forth between
* months and years.
* <p>To construct the placeholder for the calendar widget, the code is as
* follows:
* <xmp>
* <div id="calContainer"></div>
* </xmp>
* </p>
* <p>
* <strong>NOTE: As of 2.4.0, the constructor's ID argument is optional.</strong>
* The Calendar can be constructed by simply providing a container ID string,
* or a reference to a container DIV HTMLElement (the element needs to exist
* in the document).
*
* E.g.:
* <xmp>
* var c = new YAHOO.widget.Calendar("calContainer", configOptions);
* </xmp>
* or:
* <xmp>
* var containerDiv = YAHOO.util.Dom.get("calContainer");
* var c = new YAHOO.widget.Calendar(containerDiv, configOptions);
* </xmp>
* </p>
* <p>
* If not provided, the ID will be generated from the container DIV ID by adding an "_t" suffix.
* For example if an ID is not provided, and the container's ID is "calContainer", the Calendar's ID will be set to "calContainer_t".
* </p>
*
* @namespace YAHOO.widget
* @class Calendar
* @constructor
* @param {String} id optional The id of the table element that will represent the Calendar widget. As of 2.4.0, this argument is optional.
* @param {String | HTMLElement} container The id of the container div element that will wrap the Calendar table, or a reference to a DIV element which exists in the document.
* @param {Object} config optional The configuration object containing the initial configuration values for the Calendar.
