Plugins (subclasses of CGI::PageValidator::Plugin) may
require, on an individual basis, their own library data.
It may, of course, be contained within the plugin code module,
but it is encouraged to be stored in this directory separately.
The main reason is for ease-of-maintenance for the dual
front-end/back-end system. Just as the main library (MainLib/*Lib)
originates in JavaScript and is converted to Perl on the fly,
we suggest that plugin data be handled the same way.
This CGI::PageValidator system will automatically convert
your JavaScript, if supplied.
That way, you need only maintain data in a single location.
