47# the memory hierarchy: the edges are directed, from a master to a slave.
48# Initially all nodes are generated, and then all edges are added.
49# do_dot should be called with the top-most SimObject (namely root
50# but not necessarily), the output folder and the output dot source
51# filename. From the given node, both processes (node and edge creation)
52# is performed recursivly, traversing all children of the given root.

54# pydot is required. When missing, no output will be generated.
