[Insight-developers] itk::Index (signed / unsigned) long

[Miller, James V (CRD)]

I think they should to be signed quantities.  Whenever I start tiling images together, I end up
needing to put one image to the "left" of another. Having an index be signed makes this easier.

Note, the "Size" parameters are unsigned, since a negative size does not make sense.
