dotdif
 Purpose
 This function performs the dot diffusion algorithm, as first introduced by Donald Knuth [1] and improved upon by Mese and Vaidyanathan [2], given a class matrix.
 Synopsis
 y = dotdif(x, M)
 Description
 y = dotdif(x, M) converts the continuoustone, input image x of type double, into the the binary image y of type uint8(logical), using dotdiffusion according to the dither array M.
