Add a ConvertToPointCloud filter
This filter takes a DataSet
and returns a point cloud representation that
has a vertex cell associated with each point in it. This is useful for
filling in a CellSet
for data that has points but no cells. It is also
useful for operations in which you want to throw away the cell geometry and
operate on the data as a collection of disparate points.
