<p>Traverses the <a class="el" href="classStringTrieBuilder_1_1Node.html">Node</a> graph and numbers branch edges, with rightmost edges first. </p>
<p>This is to avoid writing a duplicate node twice.</p>
<p>Branch nodes in this trie data structure are not symmetric. Most branch edges "jump" to other nodes but the rightmost branch edges just continue without a jump. Therefore, write() must write the rightmost branch edge last (trie units are written backwards), and must write it at that point even if it is a duplicate of a node previously written elsewhere.</p>
<p>This function visits and marks right branch edges first. Edges are numbered with increasingly negative values because we share the offset field which gets positive values when nodes are written. A branch edge also remembers the first number for any of its edges.</p>
<p>When a further-left branch edge has a number in the range of the rightmost edge's numbers, then it will be written as part of the required right edge and we can avoid writing it first.</p>
<p>After root.markRightEdgesFirst(-1) the offsets of all nodes are negative edge numbers.</p>
