- hist must be capable of representing a vector of length
- hist must be capable of representing a column vector of length
pixel_traits<typename in_image_type>::max(). I.e. if R and C are nonzero
then they must be values that don't conflict with the previous sentence.

- #hist.size() == pixel_traits<typename in_image_type>::max()

valid i:
- hist[i] == the number of times a pixel with intensity i appears
- hist(i) == the number of times a pixel with intensity i appears
