so that the user can simply do graph.compute()... without having to specify the graph computer.
As of 3.0, we HadoopGraph does NOT have a default graph computer. This was done to not favor one technology over the other. We could allow the configuration to have a gremlin.hadoop.defaultGraphComputer=org.tinkerpop.SparkGRaphcomputer
That configuration would be carried through the various result sets so that the user would only have to choose the graph computer initially (or it is pre-selected by the graph implementation) and from that point on would be defaulted.
