Modules

Modules implement user interaction.

Modules are PHP classes derived from CModule which is derived from CWebsiteSatellite.

Modules use user provided input and web services to determine their next state. Modules use elements, layout files, configuration data to render their current state representation.

A module can render itself using different styles. A style is an identifier that is used to load a specific layout file.

Modules play a major role in the separation of concerns approach.
