Introduce common base class

UNDER COSTRUCTION, PLEASE SEE THIS POST IN RESERVE COPY

If two or more classes have common data and behavior (i.e. methods) then those classes should each inherit from a common base class which captures those data and methods. --Riel's Heuristic 5.10, Arthur Riel 1996

Example

The two classes Dog and Bird have common data (weight) and behaviour (eat() and sleep()).

A new class called Animal is created that both Dog and Bird inherit.
