Graphical display

The function 'drwpst' positions and displays partially ordered structures such as posets and bound poset algebras. In our example it works on a poset of minimal chain sequences generated by the CREP function 'mchrepfin'. While the poset data coantained in the argument 'p' are used to compute a display of the Hasse diagram of this poset, the (optional) second argument 'm' provides the function with labels for the vertices of this diagram - in the case of our example describing the minimal chain sequences represented by the corresponding vertex. Given no such optional argument the function would label the vertices just by integers.
