Add Kliesli wrapper for working with Monadic Functions

[johnmcclean]

(Functions that return a monadic type -> e.g. see #255)

[johnmcclean]

Example

Define a function that creates a Stream

import cyclops.monads.Witness.reactiveSeq;



Kleisli<reactiveSeq, Integer, Integer> k1 = t -> ReactiveSeq.iterate(0,i->i<t, i->i+1)
                                                            .anyM();

        k1.flatMap(i-> t-> ReactiveSeq.of(t+i)
                                      .anyM())
          .apply(10)
          .forEach(System.out::println);
