/**
* A function which calls the two provided functions and returns the complement of `||`ing the
* results.
* It returns false if the first function is truth-y and the complement of the second function
* otherwise. Note that this is short-circuited, meaning that the second function will not be
* invoked if the first returns a truth-y value. In short it will return true if neither predicate
* returns true.
*
* In addition to functions, `RA.neither` also accepts any fantasy-land compatible
* applicative functor.

* @param {Function} f A predicate
* @param {Function} g Another predicate
* @return {Function} Returns a function that applies its arguments to `f` and `g` and returns the complement of `||`ing their outputs together.
* @see {@link http://ramdajs.com/docs/#either|either}, {@link http://ramdajs.com/docs/#or|or}
* @example

* const f = RA.neither(gt10, even);
*
* f(12); //=> false
* f(8); //=> false
