    1. `WindowRunner` => `TimedValueProcessor` which processes 
`TimestampedValue` and emit `TriggeredOutputs` on trigger
    2. Add a subclass `DirectProcessor` which processes `TimestampedValue` with 
non-folding function (or corresponding `FunctionRunner`
    3. Change previous `DefaultWindowRunner` and `WindowRunner`
