             * 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)
