This utility should get any number of input images and do any form of operations on them including arithmetic operations (to add, subtract or multiply images) or bitwise operations (mainly used in masks for astronomical data).

If it is decided to add functions (like where below), then add simple statistical functions too, for example `min' or `max'.
Adding functions will be hard work, but it will be extremely useful.
For example
I know this is a lot of hard work! but Just for a brainstorm!
