wire simulant responds to SetSignal, observers can be added and the clock reports to the observers
refactored reception of the addobserver message to the simulant trait
added Start and StoppedAt messages for the Clock actor, however no stop condition has been defined yet
added current AgendaItem processing
added tick/tock behavior in clock
refactored processing the workitems
added test which demonstrates tiick tock progression by the clock
wiring up clock with observers and simulants observers lead to the triangle pattern: failing non-deterministic test
resolved initial wiring up, start message includes the number of components, which need to be registered, before actually starting the simulation
added test to demonstrate late registration of a component
added correct scheduling timing
working and gate, still needs some refactoring
added timing info to tick and tock, still need to include that timing info to messages
added timing information to the signal changed messages
