And/Then/When

combine sets of items emitted by two or more Observables by means of Pattern and Plan intermediaries
And/Then/When

The combination of the And, Then, and When operators behave much like the Zip operator, but they do so by means of intermediate data structures. And accepts two or more Observables and combines the emissions from each, one set at a time, into Pattern objects. Then operates on such Pattern objects, transforming them in a Plan. When in turn transforms these various Plan objects into emissions from an Observable.
