graph.cloneSubgraph(cells [, opt])
Clone the whole subgraph, including all the connected links whose source/target is in the subgraph.
This is equivalent to calling graph.cloneCells(graph.getSubgraph(cells))
.
If opt.deep
is true
, take into account embedded cells of the subgraph cells.
Return an object of the form { [original cell ID]: [clone] }
.
