Implement bitwise operators

[danielFlemstrom]

Working with packed bitmasks requires bitwise operators is not possible today.

EXAMPLE:

WATERFLAG = 2
water_mask = wqmask & WATERFLAG == WATERFLAG

and so on.....

There is a slight difference between python & and python and :
Given A and B is true and is not boolean,

A and B => B
B and A => A

A & B == B & A 

Currently, python-client outputs logical and for & operator (which needs to be addressed in that repo).
and is simply ignored.

I have made an implementation of bitwise_and, or and xor processes. I assume that if we always use bitwise operators, we should stay out of trouble famous last words....). I will post a PR later.
