ModuleEntry.h

// this file defines a function that communicates
// with the application using the module.

// input function requires a vtkPolyData and
// possible also vtkPoints as initializers.

// It then returns a vtkPolyData.

// the application is responsible for reading or creating
// data files to send as vtkPolyData,
// accepting user input for initial points,
// and handling the output polyData (either to display or
// write to file).
