This sample demonstrates a custom <a>TreeLayout</a>, ParallelLayout,
which assumes that there is a single "Split" node that is the root of a tree,
other than links that connect with a single "Merge" node.
The layout is defined in its own file, as <a href="ParallelLayout.js" target="_blank">ParallelLayout.js</a>.
</p>
<p>
Both the <a>Diagram.layout</a> and the <a>Group.layout</a> are instances of ParallelLayout,
allowing for nested layouts that appear in parallel.
