Detailed Description

Observer pattern Observer class.

This class implements the Observer in the Observer Pattern:

https://en.wikipedia.org/wiki/Observer_pattern

Observers are held by weak pointer. The order in which observers are notified is unspecified, implementation dependent, and can change at any time. Observers should NOT rely on the order in which they are added to a Subject and assume they will be called in the same order.
