Sobel / Prewitt Edge Detection

[Chris Colbert]

Hmmm, I'm not too sure of the need for this, given that ndimage already has
a Sobel and Prewitt filter which are implemented via separable 1D
convolutions (and will thus be faster than a 2D convolution). I can see this
being useful if we want to remove the dependency on ndimage at some point,
once we have our own fast convolution routine (or just have a convolution
that is faster that the one in ndimage). However in that case, I think these
two filters should still be implemented as separable 1D filters.
