[vtkusers] Combining polydata's (cleanly)

[jarv0075]

 I'm looking to combine a left and right cerebrum where there is a 'bridge'
between them which if they are placed in the same coordinate space has
overlap.

Setting the two on top of eachother is easy, but how would I go about
actually combining the two such that interior points are removed?

I don't think cleanpolydata would work for this...
