* @class vtkMoleculeAlgorithm
* @brief Superclass for algorithms that operate on
* vtkMolecules
*
*
*
* vtkMoleculeAlgorithm is a convenience class to make writing algorithms
* easier. 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 vtkMolecules. If that isn't the case
* then please override this method in your subclass. You should implement
* the subclass's algorithm into RequestData( request, inputVec, outputVec).
