Normally you won't need to use this singleton directly. 99% of the cases you will use the CCNode interface,
which uses this singleton.
But there are some cases where you might need to use this singleton.
Examples:
- When you want to run an action where the target is different from a CCNode.
- When you want to pause / resume the actions
