Example of using the Strategy Pattern.

The Strategy pattern provides a way to easily assign different algorithms to a class instance that can be changed at the time the class is created.

In this exercise, the Strategy_ShowEntries_Class instance sorts and displays a list of EntryInformation elements. Three different sorting strategies are provided (Name, Age, Height) and an option to reverse the normal order of the sort.
