// .NAME vtkPythonAlgorithm - algorithm that can be implemented in Python
// .SECTION Description
// vtkPythonAlgorithm is an algorithm that calls a Python object to do the actual
// work.
// It defers the following methods to Python:
// - ProcessRequest()
// - FillInputPortInformation()
// - FillOutputPortInformation()
//
// Python signature of these methods is as follows:
// - ProcessRequest(self, vtkself, request, inInfo, outInfo) : vtkself is the vtk object, inInfo is a tuple of information objects
// - FillInputPortInformation(self, vtkself, port, info)
// - FillOutputPortInformation(self, vtkself, port, info)
// - Initialize(self, vtkself)
//
// In addition, it calls an Initialize() method when setting the Python
// object, which allows the initialization of number of input and output
// ports etc.
// .SECTION See Also

// Specify the Python object to use to operate on the data. A reference will

// ports as well as perform tasks commonly performed in the constructor
// of C++ algorithm subclass.

// Description:
// Set the number of input ports used by the algorithm.
// This is made public so that it can be called from Python.
