7  Synopsis [Implements the partition of the network with respect to the
8  nodes that comprise the submodules boundaries.]
9
10  Description [The network is composed of an arbitrary set of nodes, each of
11  them implementing some function. This partitioning method will produce a
12  graph representing the network in which the nodes that constitute submodule
13  boundaries will be preserved in the graph structure.]
