Amber project being application and library at once

This shows dual nature of application and library in an amber project

A --|> B means "A is-a B".

A ---> B means "A has-a B".

A - - - X means "Note regarding A: X".

Note: Theoretically, an Application can exist without having code of its own. That's why there is no relation between Application and AmberCodeModule. In general case, of course, Amber project has its own code and its Application role embraces it along with all the dependent code.
