<p>
This makes use of the "ScrollingTable" Panel defined in <a href="ScrollingTable.js">ScrollingTable.js</a>.
The "AutoRepeatButton" Panel is also defined in that file.
Each node is resizable.
</p>
<p>
Note how links connect particular port elements on each node.
When an element has a <a>GraphObject.index</a> less than the <a>Panel.topIndex</a>,
the panel arranges it be zero sized at the top of the panel.
Similarly, elements beyond the last item in the panel are arranged to have zero size and be at the end of the list,
which will be at the bottom of the panel.
