+// .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. 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 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 separate functions such as
+// RequestDataObject RequestData and RequestInformation. The default
+// implementation of RequestDataObject will create an output data of the
+// same type as the input.
