[vtkusers] vtkStringArray with heterogeneous number of components?

[Tanaka Simon]

Hi David,

+1 for the vtkVariantArray which is good to know.

As you suggested, i implemented a "\t" tab delimiter approach which 
works fine. however, it kind of kills the idea of using a standard to 
represent data...

thanks for your help
