Superclass for algorithms that produce only PistonDataObjects.
vtkPistonAlgorithm is a convenience class to make writing algorithms that operate in piston space easer. Basically one does that by subclassing this class and overriding Execute() to call into a method that calls into an external function compiled with the cuda compiler.
There are some assumptions and defaults made by this class you should be aware of. This class defaults such that your filter will have one input port and one output port. If that is not the case simply change it with SetNumberOfInputPorts etc. See this class constructor for the default. This class also provides a FillInputPortInfo method that by default says that all inputs will be PistonDataObject. If that isn't the case then please override this method in your subclass. This class breaks out the downstream requests into separate functions such as ExecuteData and ExecuteInformation.

Typically Execute uses this to copy input bounds to output. Algorithms for which this heuristic is poor, should override and do it exactly, perhaps by asking the GPU to calculate it,
