 This class defines a PN actor object. This actor is automatically
 generated, as part of the <A
 HREF="http://www.gigascale.org/compaan">Compaan</A> project. Although
 most of the actor is generated automatically, some parts have been
 manually tuned for this demo especially when reading and writing of
 matrices is involved; they may change in future releases.
