    * The Calendar component is a UI control that enables users to choose one or more dates from a graphical calendar presented in a one-month or

    /**
    * 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.
