<p>
This defines a node template consisting of a top half and a bottom half.
Each half's text and color are data bound.
However the size of each node is fixed, so if the text is too long, it will be clipped.
</p>
<p>
The "RoundedTopRectangle" and "RoundedBottomRectangle" figures are defined in
<a href="../extensions/RoundedRectangles.js">RoundedRectangles.js</a> in the extensions directory.
See also the <a href="roundedGroups.html" target="_blank">Rounded Groups</a> sample.
