find_bridges(mpc)

find_bridges() - Finds bridges in a network.

[ISLANDS, BRIDGES, NONBRIDGES] = FIND_BRIDGES(MPC)

Returns the islands, bridges and non-bridges in a network.
Bridges are filtered out using Tarjan's algorithm. A BRIDGE is a branch
whose removal breaks the island to multiple parts. The return value BRIDGES
is a cell array of vectors of the bus indices for each island.
