*
* var c = new YAHOO.widget.Calendar("calContainer", configOptions);

*
* var containerDiv = YAHOO.util.Dom.get("calContainer");
* var c = new YAHOO.widget.Calendar(containerDiv, configOptions);
*
*
*
* 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".
