API >> mvc

This contains all your MVC elements.
If you will need a file to always be executed before or after the application it will need to be placed in here. It is recommended to name the files appConstruct and appDestruct. Users of CakePHP may prefer the file to be called appController. It does not matter what the file is named as long as the filename matches the class-name inside it and that the filename is defined in the .config
