Consider dropping custom Python operators

[pombredanne]

@Kronuz @bastikr I am not sure that I have a need to build boolean expression using overloaded operators in Python and this introduces subtle bias and behaviors in many places.

Do you have a use for them? (as opposed to build an expression from a parsed string or building an expression from nested Python objects)

This would mean dropping the dunder methods from here:

boolean.py/boolean/boolean.py

Line 730 in 3746d22

def __and__(self, other):

__and__ , __mul__ , __invert__ , __or__ and __add__ and possibly __nonzero__ and __bool__

This would eventually keep the python boolean logic completely separate from this library boolean logic.

Alternatively, this could be something that could be made optional and not available on a systematic basis.

Ping? any feedback on this?
