[vtkusers] Attaching meta data to vtkPolyline/vtkPolydata

[Alex Malyushytskyy]

Polydata can manage data associated with nodes ( scales number of nodes),
cell or with polydata  itself.
In general you are forced to put arrays into nodal or cell data in order to
display them, but you might chose to store any type of your data in above
mentioned forms.
It is entirely up to you,
