TITLE           Sort Tree Topology

OCCURRENCE      ARB_NT/Tree/Beautify tree/...

                ARB_PARSIMONY/Tree/Beautify tree

DESCRIPTION     Arranges branches and groups according to the size of each 
                subtree. If the size doesn't differ at a furcation, subtrees
                will be sorted alphabethically. This ensures the sorting is stable.

                Sorting does not change the tree topology, it only swaps branches!
                
SECTION         Available sort modes

                The first sort mode sorts the bigger branches to the top, 
                the third sorts them to the bottom.

                The second sort mode sorts the bigger branches to the edges of the 
                tree and the smaller branches to the center.

                The fourth and fifth mode are designed to sort the tree for 
                the radial tree display mode. 

                The fourth mode does the opposite of the second mode: it sorts 
                bigger branches to the center and smaller ones to the borders 
                of the tree.

                The fifth mode alternates between second and fourth mode.

NOTES           This facilitates the comparison of tree topologies resulting
                from different treeing approaches.

                See also LINK{resortbyother.hlp}.

                In ARB_PARSIMONY you cannot select the beautification method: it will
                always sort bigger branches to top. This will also happen automatically
                after LINK{pa_optimizer.hlp}.
