// .NAME vtkDirectedAcyclicGraph - A rooted tree data structure.
//
// .SECTION Description
// vtkDirectedAcyclicGraph is a connected directed graph with no cycles. A tree is a type of
// directed graph, so works with all graph algorithms.
//
// vtkDirectedAcyclicGraph is a read-only data structure.
// To construct a tree, create an instance of vtkMutableDirectedGraph.
// Add vertices and edges with AddVertex() and AddEdge(). You may alternately
// start by adding a single vertex as the root then call graph->AddChild(parent)
// which adds a new vertex and connects the parent to the child.
// The tree MUST have all edges in the proper direction, from parent to child.
// After building the tree, call tree->CheckedShallowCopy(graph) to copy the
// structure into a vtkDirectedAcyclicGraph. This method will return false if the graph is
// an invalid tree.
//
// vtkDirectedAcyclicGraph provides some convenience methods for obtaining the parent and
// children of a vertex, for finding the root, and determining if a vertex
// is a leaf (a vertex with no children).
