Supporting ReactiveSwift events

[a-voronov]

Now we can mock calls with Signal.Event or sequence of them (corresponding to Event contract)
i.e. comparing Result with Signal.Event:

sut.sum.on { $0.right == 15 }.returns(.success(7))
// is identical to:
sut.sum.on { $0.right == 15 }.returns([.value(7), .completed])
// or this, since it adds completion event in the end of events sequence
// and if there’s no terminating event, complete will fire
// otherwise signal will terminate with any terminating event and stop sending any further events (see Event contract)
sut.sum.on { $0.right == 15 }.returns(.value(7))

and you can also have sequence of value events:

sut.fact.returns([.value(1), .value(1), .value(2), .value(6), .value(24), .completed])

will add more tests for sequence of events, but idea stays the same :)

yep, seems like we need Danger 😅
