to nx-cugraph.This includes a test, but relies largely on the existing test coverage provided by NetworkX. The test included here could (should) be submitted to NetworkX though in a separate PR, since it is not covering anything unique to nx-cugraph.
A benchmark is also included, with results showing 2-4X speedup. I've seen much, much larger speedup on a different graph (large movie review bipartite graph, showing 966s for NX, 2s for nx-cugraph = ~500X), so I need to investigate further. This investigation need not prevent this PR from being merged now though.
