[Python-ideas] Add Binary module.

This module should contain operations that can be performed on binary numbers. In the below examples a and b are binary numbers. binary.add(a,b) binary.sub(a,b) binary.mul(a,b) binary.div(a,b) binary.ones_complement(a) //returns 1's complement of a. binary.twos_complement(a) //returns 2's complement of a. binary.dectobi(a) //converts decimal "a" to binary of "a". binary.bcd(a) //returns bcd of a. binary.gray(a) //returns grey code of a. binary.min() //minimizes. binarybitodec //converts binar "a" to decimal of "a".
