// .NAME vtkDataObjectAlgorithm - Superclass for algorithms that produce only data object as output
// .SECTION Description
// vtkDataObjectAlgorithm 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
// constructor for the default. This class also provides a FillInputPortInfo
// method that by default says that all inputs will be DataObject. 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
// ExecuteData and ExecuteInformation. For new algorithms you should
// implement RequestData( request, inputVec, outputVec) but for older filters
// there is a default implementation that calls the old ExecuteData(output)
// signature, for even older filters that don;t implement ExecuteData the
// default implementation calls the even older Execute() signature.
