# Solve the blob-o'-resistors from xkcd #730, Circuit Diagram.  This
#  version separates the two nodes shorted together near the middle of
#  the blob (they're nodes 7a and 7b).  This doesn't affect any
#  currents through any resistors or the overall resistance, but it
#  does let us see how much current that short is carrying.
#
# This assumes the voltage across the network is 1V.
