/**
 * This is the main program, where all the magic happens
 * 
 * I used a customized version of swagger.io (I intented to build something more light that will easly run under a nano aws instance)
 *
 * HTTP calls will arrive here like this: GET /airport or GET /airport/YUL
 * the first portion (airport) will indicate wich file controller will be included (./api/AirportApiController.php)
 * the other parts will serve as filtering parameters or ID, the method will decide what to do with them.
