/*
* The Observer Pattern
*
* Example:
* A publisher creates a new magazine and begins publishing issues.
* You subscribve and receive issues as along as you stay subscribed.
* You can unsubscribe at any time.
* Others can also subscribe.
* Other can also unsubscribe.
* If Publisher ceases business, you stop receiving issues.
*
* Allows:
* -Subjests and Observers are "loosely coupled"
* -Strive for loosely coupled designs between objects that interact. (Design Principle #4)
*
* Implementation (Push):
*
* We define 3 interfaces:
* -ISubject (implemented by publisher, stores the list of subscribers, notifies on updates)
* -IObserver (implemented by subscriber, update method)
* -IDisplayElement (implemented by subscriber, display method)
*
* We define main class WatherData:
* -WatherData that implements ISubject
* -Notifies observers(subscribers) though method Update()
* -This doesn't know anything about observers
* -Subject doesn't care it keeps doing its job
*
* We define subscriber classes:
* -Each implements interfaces IObserver and IDisplayElement just to display info
* -Each receives Subject(Publisher) in constructor, subscribes itself to it, and keeps it in private field
* -To become an observer it needs to implement IObserver
*
