[Paraview] display boundaries of 2D geometry

[Cory Quammen]

Hi Matthais,

People typically use multi-block data sets for this purpose. ParaView
has a multi-block inspector that enables you change the visibility of
the blocks in a data set. If you make each surface a block, then you
can show/hide each at will.

HTH,
Cory
