<p class="short-description">The Structures_Graph_Manipulator_TopologicalSorter is a manipulator  which is able to return the set of nodes in a graph, sorted by topological  order.</p>
<p class="description"><p>A graph may only be sorted topologically iff it's a DAG. You can test it  with the Structures_Graph_Manipulator_AcyclicTest.</p></p>
