title: jung2: how to draw a graph as a tree?
body: <p>I need to draw my graph that has a root node and childs have crossrelations between them as standard graphviz draw algorithm. Root on the top, childs 
  below. Treelayout and RadialTreeLayout do not suit (not strong tree and show buggy view for my tree when it's tree). Is there a way to draw a graph as graphviz without Forest and  TreeLayout, RadialTreeLayout? I can't find standard layout for SparseMultigraph that does that.</p>
