/** @brief Scheduler is responsible of triggering the scheduled callbacks.

You should not use NSTimer. Instead use this class.
|
|
|
|
There are 2 different types of callbacks (selectors):
|
|
|
|
- update selector: the 'update' selector will be called every frame. You can customize the priority.
|
|
- custom selector: A custom selector will be called every frame, or with a custom interval of time
|
|
|
|
The 'custom selectors' should be avoided when possible. It is faster, and consumes less memory to use the 'update selector'.
