Takes RGB images in 24 bpp and computes the 3D histogram of such an image. I.e., splits every axis into 'n' bins thus making n^3 bins in total and shows the result in the form of 'bubbles' of different size within the RGB cube.

The function can be controlled by parameters. Besides the graphics produced, it can output also numerical results.

A short demo is included.

It should be noted that the very first inspiration came from seeing similar histograms at web page
