Hi

gray2ind should return an image of the uint8 or uint16 class as per matlab
documentation. Since there is no description of what happens when not even
uint16 is enough, I made it return an indexed image of class double. Note that
there's an offset of 1 depending on the class.

I have also extended it accept binary images with n defaulting to 2 in such
cases.
