/**
 * Response.php - The Jaxon Response
 *
 * This class collects commands to be sent back to the browser in response to a jaxon request.
 * Commands are encoded and packaged in json format.
 *
 * Common commands include:
 * - <Response->assign>: Assign a value to an element's attribute.
 * - <Response->append>: Append a value on to an element's attribute.
 * - <Response->script>: Execute a portion of javascript code.
 * - <Response->call>: Execute an existing javascript function.
 * - <Response->alert>: Display an alert dialog to the user.
 *
 * Elements are identified by the value of the HTML id attribute.
