An OLAP oriented step for doing IO operations with {@link GraphTraversalSource#io(String)} which uses the
{@link CloneVertexProgram} for its implementation. Standard Hadoop OLAP configurations can be passed using the
{@link GraphTraversal#with(String, Object)} step modulator as all options aside from those in {@link IO} will be
transferred.
