[vtkusers] vtkDataObject::SeriesLength

[Gerald Dalley]

I am extending the VTK hierarchy to do some 3D registration work.  In the
process of doing this, I am currently implementing a new vtkDataObject,
vtkDataSetCluster that groups sets of vtkDataSet objects together.  While
going through the existing source code, I noticed an unused internal
attribute, vtkDataObject::SeriesLength with the comment: "Support for
processing series of data sets."  It sounds to me that once implemented, a
vtkPolyData with a series length of 10, for example, would be a super
vtkPolyData collection of 10 of the current vtkPolyData objects in it.  Am I
guessing correctly, or is the SeriesLength to be used for something totally
different (e.g. streaming)?
