[jeremydmiller]

IPollingJob

Start() Stop() WaitForNextRunToComplete()

PollingJobCoordinator

ctor(IPollingJob*) makes sure that the activation and deactivation happens and messages w/ EventAggregator

PollingJobActivator --> IActivator PollingJobDeactivator --> IDeactivator

• Register PollingJobCoordinator & the activator/deactivator if Bottles.Services is present (?)
