Functionality to display a data dictionary for any database on the server.
This defaults to displaying a webpage (index.php) and can also create
csv and xml files.
Developed and tested on a MySQL server; however, since it uses the PDO
library, this ought to be usable on any type of database server that a) is
supported by PDO, and b) uses the information_schema database as per the
ANSI standards.
This is for development use only. Do not use on a production server or
anywhere else publicly accessible. Like phpinfo(), this might give people
information that you don't want them to have. Use at your own risk.
