a simple fast 2D graph layout that looks for a 'constraint' array (vtkDoubleArray).
Any entry in the constraint array will indicate the level of impedance a node has to the force calculations during the layout optimization. The array is assumed to be normalized between zero and one, with one being totally constrained, so no force will be applied to the node (i.e. no movement), and zero being full range of movement (no constraints).
This class is a density grid based force directed layout strategy. Also please note that 'fast' is relative to quite slow. :) The layout running time is O(V+E) with an extremely high constant.
