### Description

not2 is a function adaptor, known as a negator, that takes a binary predicate function object as its argument and returns a binary predicate function object that is the complement of the original. binary_negate is a function object class that includes a return type for the not2 negator.

Note that not2 works only with function objects that are defined as subclasses of the class binary_function.
