Class: xajax
The xajax 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 <xajaxResponse>). Many flags and settings can be
adjusted to effect the behavior of the xajax class as well as the client-side
javascript.

Array: aSettings
This array is used to store all the configuration settings that are set during
the run of the script. This provides a single data store for the settings

wish to track, however, settings are available via a reference to the <xajax>
