> Currently, all the methods that have non-deterministic behavior such as coin and sample have no ability to set a seed. The ability to set a seed will allow for reproducible and testable behavior as well as more control flow for random processes. If a certain backend does not support seeding, they could simply ignore it. Some possible API changes:
> graph.traversal.V().withSeed(2L).coin(.5)
> graph.traversal.V().sample(3, 0L)
