Method createInternalNode

src/figtree/treeviewer/ReRootedTree.java:152–163

Once a SimpleRootedTree has been created, the node stucture can be created by calling createExternalNode and createInternalNode. First of all createExternalNode is called giving Taxon objects for the external nodes. Then these are put into sets and passed to createInternalNode to create a parent of
