- * Class: mxParallelEdgeLayout
- * 
- * Extends <mxGraphLayout> for arranging parallel edges. This layout works
- * on edges for all pairs of vertices where there is more than one edge
- * connecting the latter.
- * 
- * Example:
- * 
- * (code)
- * var layout = new mxParallelEdgeLayout(graph);
- * layout.execute(graph.getDefaultParent());
- * (end)
- * 
- * Constructor: mxCompactTreeLayout
- * 
- * Constructs a new fast organic layout for the specified graph.
