a simple 2D graph layout
This class is an implementation of the work presented in: Fruchterman & Reingold "Graph Drawing by Force-directed Placement" Software-Practice and Experience 21(11) 1991). The class includes some optimizations but nothing too fancy.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Seed the random number generator used to jitter point positions. This has a significant effect on their final positions when the layout is complete.

Set/Get the maximum number of iterations to be used. The higher this number, the more iterations through the algorithm is possible, and thus, the more the graph gets modified. The default is '100' for no particular reason Note: The strong recommendation is that you do not change this parameter. :)

Set/Get the number of iterations per layout. The only use for this ivar is for the application to do visualizations of the layout before it's complete. The default is '100' to match the default 'MaxNumberOfIterations' Note: Changing this parameter is just fine :)

Set/Get the Cool-down rate. The higher this number is, the longer it will take to "cool-down", and thus, the more the graph will be modified. The default is '10' for no particular reason. Note: The strong recommendation is that you do not change this parameter. :)

Set Random jitter of the nodes at initialization to on or off. Note: It's strongly recommendation to have jitter ON even if you have initial coordinates in your graph. Default is ON

This strategy sets up some data structures for faster processing of each Layout() call

This is the layout method where the graph that was set in SetGraph() is laid out. The method can either entirely layout the graph or iteratively lay out the graph. If you have an iterative layout please implement the IsLayoutComplete() method.
Implements vtkGraphLayoutStrategy.

I'm an iterative layout so this method lets the caller know if I'm done laying out the graph
