> {{GraphFilterStrategy}} would be a {{TraversalStrategy}} for {{GraphComputers}}. It will inspect the {{Traversal}} and decide the {{computer.vertices(...).edges(...)}} to use.
> Some rules:
> 1. If the traversal is part of an OLAP chain, don't apply strategy.
> 2. If the traversal is persist edges, then don't {{edges(...)}} or {{vertices(...)}}.
> 3. If the traversal is persist vertex properties, then don't do {{vertices(...)}}.
> Shouldn't be too difficult. Basically looking for:
> 1. {{VertexStep}} labels for edges.
> 2. {{HasStep}} containers for vertices and edges.
> From there, we can get fancy with {{outE().has("stars",gt(4))}}-style {{edges(...)}}. However, basic element-label based filtering should be easy.
