Web services (2.0 onwards)

This is a work in progress. Please don't try following it just yet.

Overview

Web services are built and provided the the 'externallib.php' file in the modules (or areas) directory. In this file is kept the external class that extends the 'external_api' class and provides definitions for the incoming message format, outgoing message format and the worker functions for each service.
