Function cnetworks::stitch_together

pub fn stitch_together(net: &mut Network)

Stich the network together if it is not whole.

A random element of net is chosen as the root and the ‘main’ network is it’s reachable teritory. From the unreachable teritory a random node is chosen and connected to a random elemnt of the ‘main’ network, thus marking it and its reachable teritory as no longer unreachable. The process is repeated until there are no unreachable nodes left.
