[Insight-developers] itkVTKPolyDataReader.h reads ascii only --- why?

[Alexandre GOUAILLARD]

hi wanlin, all,

mesh IO is in my pile of to-be-reviewed. I m goign to put it on the
top of my pile, and address it early next week. If everything goes
alright, I would push the code in ITK v4 before the end of next week.

thanks for the contribution.

alex.
