Detailed Description

The TaskScheduler class provides the ability to schedule std::function's in the near future. Use TaskScheduler::Update to update the scheduler. Popular methods are:

• Schedule (Schedules a std::function which will be executed in the near future).
• Schedules an asynchronous function which will be executed at the next update tick.
• Cancel, Delay & Reschedule (Methods to manipulate already scheduled tasks). Tasks are organized in groups (uint), multiple tasks can have the same group id, you can provide a group or not, but keep in mind that you can only manipulate specific tasks through its group id! Tasks callbacks use the function signature void(TaskContext) where TaskContext provides access to the function schedule plan which makes it possible to repeat the task with the same duration or a new one. It also provides access to the repeat counter which is useful for task that repeat itself often but behave different every time (spoken event dialogs for example).
