* More info: https://en.wikipedia.org/wiki/Chain-of-responsibility_pattern
* http://www.dofactory.com/net/chain-of-responsibility-design-pattern
* What problems can the Chain of Responsibility design pattern solve?
* Coupling the sender of a request to its receiver should be avoided.
* It should be possible that more than one receiver can handle a request.
*
* Implementing a request directly within the class that sends the request is inflexible because it couples the class to a particular receiver and makes it impossible
* to support multiple receivers.
