combine(java.util.function.BinaryOperator<Combiner<T>> combiner,
Combiner<T> app)
Combine two applicatives together using the provided BinaryOperator (Semigroup, Monoid and Reducer all
extend BinaryOperator - checkout Semigroups and Monoids for a large number of canned combinations).

default <T2,R> Functor<R> |
combine(Value<? extends T2> app,
java.util.function.BiFunction<? super T,? super T2,? extends R> fn)
Lazily combine this ApplicativeFunctor with the supplied value via the supplied BiFunction

To lift any Semigroup (or monoid) up to handling Applicatives use the combineApplicatives operator in Semigroups
{@see com.aol.cyclops.Semigroups#combineApplicatives(BiFunction) } or Monoids
{ {@see com.aol.cyclops.Monoids#combineApplicatives(java.util.function.Function, com.aol.cyclops.Monoid)
}
{@code
BinaryOperator> sumMaybes = Semigroups.combineScalarFunctors(Semigroups.intSum);
Maybe.just(1)
.combine(sumMaybes, Maybe.just(5))
//Maybe.just(6));
