Detailed Description

Defer signal changes until later time.

This is mainly usedful to allow making multiple changes with only one signal being emitted.

Effects:

• Blocks sending signals until Deferrer expires (destroyed or manually reset).
• When a deferrer is expired a signal will be emitted (if there are multiple deferrers each will emit a signal).
