/**
 * Jaxon.php - Jaxon class
 *
 * The Jaxon class uses a modular plug-in system to facilitate the processing
 * of special Ajax requests made by a PHP page.
 * It generates Javascript that the page must include in order to make requests.
 * It handles the output of response commands (see <Jaxon\Response\Response>).
 * Many flags and settings can be adjusted to effect the behavior of the Jaxon class
 * as well as the client-side javascript.
