Currently, looking at the other image processing algorithms in the GIL,
most of them have an implementation for a single channel(i.e: grayscale)
and then this is extended to work with multi-channel by iterating over the
channels. Right now, we have so many questions, so why not to do the same
with histogram too? will make things simpler and also as we'd have some
basic implementation we'll know where to take things further.
