Test2::Compare::Negatable - Poor mans 'role' for compare objects that can be negated.

       $bool = $obj->negate
       $obj->set_negate($bool)
       $attr = NEGATE()
           The NEGATE attribute will be added via Test2::Util::HashBase.

       Using this package inside an Test2::Compare::Base subclass will overload "!$obj" and import
       clone_negate() and toggle_negate().

       $clone = $obj->clone_negate()
           Create a shallow copy of the object, and call "toggle_negate" on it.

       $obj->toggle_negate()
           Toggle the negate attribute. If the attribute was on it will now be off, if it was off it will now be
           on.

       Until perl 5.18 the 'fallback' parameter to overload would not be inherited, so we cannot use inheritance
       for the behavior we actually want. This module works around the problem by emulating the "use overload"
       call we want for each consumer class.
