// .NAME vtkDataSetAlgorithm - Superclass for algorithms that produce output of the same type as input
// .SECTION Description
// vtkDataSetAlgorithm is a convenience class to make writing algorithms
// easier. It is also designed to help transition old algorithms to the new
// pipeline architecture. Ther 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 classes
// contstructor for the default. This class also provides a FillInputPortInfo
// method that by default says that all inputs will be DataSet. If that isn't
// the case then please override this method in your subclass. This class
// breaks out the downstream requests into seperate functions such as
// RequestDataObject RequestData and RequestInformation. The default
// implementation of RequestDataObject will create an output data of the
// same type as the input.
