A dialog task is a

1. single IDialogStack stack of IDialog frames, waiting on the next IActivity
2. the IEventProducer<Event> queue of activity events necessary to satisfy those waits
3. the IEventLoop loop to execute that dialog code once the waits are satisfied

Extension Methods

Wait(IDialogStack, ResumeAfter<IMessageActivity>)	Suspend the current dialog until the user has sent a message to the bot.
InterruptAsync<T,R>(IDialogTask, IDialog<T>, R, CancellationToken)	Interrupt the waiting dialog with a new dialog
