//
// ajax.js
//
// provides a function that sends AJAX requests to the App::MFILE::WWW server
// (which forwards them to the backend server) and takes action based on the
// HTTP response received.
//
// The 'ajax' function takes three arguments:
// - MFILE AJAX Object (an object)
// - success callback 
// - failure callback
//
// The success and failure callbacks can be null or undefined, in which case App::MFILE::WWW will
// just display the status text in the #result div (i.e., the line at the bottom of the frame).
// If your AJAX calls needs any other handling than this, you need to provide at least a success
// callback.
//
// In all cases except login/logout, the MFILE AJAX Object looks like this:
// {
//     "method": any HTTP method accepted by the backend server
//     "path": valid path to backend server resource
//     "body": content body to be sent to backend server (can be null)
// }
//
// MFILE AJAX Object for _login_ to backend server:
// {
//     "method": "LOGIN",
//     "path": "login",
//     "body": { "nam": $USERNAME, "pas": $PASSWORD }
// }
//
// MFILE AJAX Object for _logout_ from backend server:
// {
//     "method": "LOGIN",
//     "path": "logout",
//     "body": null
// }
//
// For details on how AJAX calls are handled, see lib/App/MFILE/WWW/Resource.pm
