public void <B>layoutGraph</B>()</PRE>
<DL>
<DD>This method does a complete layout of the graph which includes
 removing cycles, assigning levels to nodes, reducing edge crossings
 and laying out the vertices horizontally for better visibility.
 The removing of cycles and assignment of levels is only performed
 if hasn't been performed earlier or if some layout option has been
 changed and it is necessary to do so. It is necessary to do so,
 if the user selects/deselects edge concentration or topdown/bottomup
 options.
 <p> The layout is performed in a separate thread and the progress
 bar of the class is updated for each of the steps as the process
 continues.
