com.opengamma.engine.depgraph.DependencyNodeFilter
Strategy for filtering a dependency graph to produce a sub-graph.
This interface is used to decide whether a specific node should be included in the sub-graph.

   * @param calcConfName calculation configuration name
   * @return a dependency graph with any nodes which have already been satisfied filtered out, not null See {@link #computeDelta} and how it calls {@link #markExecuted}.
