##########################################################################

Seeing as each page has to manage its wiki separately (for performance 
reasons - JOINs instead of multiple queries), this class is rather bare.

The only useful function in here is revision_history(). It creates a 
table with the revision history for that particular wiki page. 


class_wiki depends on your wiki table being structured like this:

+------------+--------------+------+-----+----------------------+-------+
| Field		 | Type			| Null | Key | Default				| Extra |
+------------+--------------+------+-----+----------------------+-------+
| RevisionID | int(12)		| NO   | PRI | 0					|		|
| PageID	 | int(10)		| NO   | MUL | 0					|		|
| Body		 | text			| YES  |	 | NULL					|		|
| UserID	 | int(10)		| NO   | MUL | 0					|		|
| Summary	 | varchar(100) | YES  |	 | NULL					|		|
| Time		 | datetime		| NO   | MUL | 0000-00-00 00:00:00  |		|
+------------+--------------+------+-----+----------------------+-------+

It is also recommended that you have a field in the main table for 
whatever the page is (e.g. details.php main table = torrents), so you can
do a JOIN.
