TITLE		Store Tree Topologies

OCCURRENCE	ARB_PARSIMONY <Stack> button

DESCRIPTION	Allows to temporarily store tree topologies.

		Click on the <STORE> button to store the current tree. The number of
                stored tree topologies is shown in the 'Stack'
                subwindow.

		After performing further optimizations, any new tree topology
                can be added to the stack by clicking on <STORE> again.

		Click on the <RESTORE> button to restore stored trees. Your current tree
                will be discarded.

NOTES		The initial tree will be stored at program start-up.

                When you restore the last tree from the tree stack it will be stored again automatically,
                to support further restores.

EXAMPLES	None

WARNINGS	The trees stored in the stack are lost when you close the 'ARB PARSIMONY window'.

BUGS		No bugs known
