/**
 * Ofcos the classes should be in different files
 * Assumes you are using a command bus to raise events I happen to love Jeff Way https://github.com/laracasts/Commander
 *
 * With this architecture you don't need to modify any existing classes for new headers just add a new class and should work
 * 
 * More than one class can handle the requests
