==Tips==

Start by creating mock-up classes (class declaration and definition with empty methods that only compiles and don't do anything).

Each class MUST have its own header file to hold its declaration and "cpp" file to hold its implementation. To make sure you do not do circular includes follow these simple guidelines:

* Use includes only in files in which the actual header file code is used.

* '''Avoid "just in case" includes.'''

==File Names==

Use the following rules to create filenames for your class.
