// .NAME vtkSimple3DCirclesStrategy - places vertices on circles in 3D
//
// .SECTION Description
// Places vertices on circles depending on the graph vertices hierarchy level.
// The source graph could be vtkDirectedAcyclicGraph or vtkDirectedGraph if MarkedStartPoints array was added.
// The algorithm collects the standalone points, too and take them to a separated circle. If method is FixedRadiusMethod,
// the radius of the circles will be equal. If method is FixedDistanceMethod, the distance beetwen the points on circles will
// be equal.
//
// In first step initial points are searched. A point is initial, if its in degree equal zero and out degree is greater than zero (or
// marked by MarkedStartVertices and out degree is greater than zero). Independent vertices (in and out degree equal zero) are collected
// separatelly. In second step the hierarchical level is generated for every vertex. In third step the hierarchical order is generated.
// If a vertex has no hierarchical level and it is not independent, the graph has loop so the algorithm exit with error message. Finally
// the vertices positions are calculated by the hierarchical order and by the vertices hierarchy levels.
