separated out submit() and preparation of traversal for graph computer. Added ScriptTraversal interface and GroovyTraversal instance. In theory, there will be ScalaTraversal, JavaScriptTraversal that will allow Gremlin langauge dialets to be run over OLAP. The proof of the simplicity is seen in GiraphRemoteAcceptor. Also, ComputerResult memory in OLAP are added to the subsequent ComputerResultStep traversal.
