/*
* The Strategy Pattern
*
* Defines a family of algorithms, encapsulates each one, and makes them interchangable.
* Strategy lets the algorithm vary dependently from clients that use it.
*
* Solves problems:
* -behaviors defined at compilation not runtime
* -decereased code flexibility
* -duplicate the code
*
* Allows:
* -interchangeable algorithms for behavior for each object
* -change behaviors at runtime
* -common behaviors code can be reused as behaviours can be shared
* -Favor composition over inheritance. (Design Principle #3)
* -Program to an interface not implementation. (Design Principle #2)
* -Identify the aspect of your code that vary and separate them from what stays the same.[Encapsulate What Varies] (Design Principle #1)
