There out to be a convenient way to resplit, say, a simulated multilayer network into individual layers. It should probably have an output=c("attributes","list") argument, with the former producing a single network with an edge attribute for each layer and the latter producing a list of networks, one for each layer.

It will also need to put bipartite, undirected, etc. attributes back.
