public String getDisplayText() {
		return getName();
	}
Returns the display text for the node. By default, this is the same as the name of the node.
The name of the node usually serves two purposes: 1) to uniquely identify the node (the
identity) and 2) the display text (what you see in the tree). Sometimes, it is useful to
display more information in the tree without affecting the nodes identity. In this case, you
can override this method to return the "display" name, while {@link #getName()} will still
return the name used to identify the node.

@return the display text for the node.
