* @param oData {object} a string or object containing the data that will

* Providing a string is the same as providing an object with a single property named html.
* All values in the oData will be used to set equally named properties in the node
* as long as the node does have such properties, they are not undefined, private or functions.
* All other attributes are made available in noderef.data, which
* can be used to store custom attributes. TreeView.getNode(s)ByProperty
* can be used to retrieve a node by one of the attributes.
* @param oParent {YAHOO.widget.Node} this node's parent node
* @param expanded {boolean} the initial expanded/collapsed state (deprecated; use oData.expanded)
* @param hasIcon {boolean} specifies whether or not leaf nodes should
* be rendered with or without a horizontal line line and/or toggle icon. If the icon
* is not displayed, the content fills the space it would have occupied.
* This option operates independently of the leaf node presentation logic
* for dynamic nodes.
