 		* PLUGGING INTO USER PAGES

 		* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 		* Userpages are highly programmable and extendable using a number of

 		* hooks. These hooks are:

 		*

 		*   - userpage_sidebar_left

 		*   - userpage_sidebar_right

 		*   - userpage_tabs_links

 		*   - userpage_tabs_body

 		*

 		* You can add a variety of sections to user pages, including new tabs

 		* and new sections on the tables. To add a tab, attach to

 		* userpage_tabs_links and echo out:

 		*

 		*   <li><a href="#tab:YOURTABID">YOUR TAB TEXT</a></li>

 		*

 		* Then hook into userpage_tabs_body and echo out:

 		*

 		*   <div id="tab:YOURTABID">YOUR TAB CONTENT</div>

 		*

 		* The userpage javascript runtime will take care of everything else,

 		* meaning transitions, click events, etc. Currently it's not possible

 		* to add custom click events to tabs, but any DOM-related JS that needs

 		* to run in your tab can be run onload and the effects will be seen when

 		* your tab is clicked. YOURTABID should be lowercase alphanumeric and

 		* have a short prefix so as to assure that it remains specific to your

 		* plugin.

 		*

 		* To hook into the "profile" tab, use userpage_sidebar_{left,right}. Just

 		* echo out table cells as normal. The table on the left (the wide one) has

 		* four columns, and the one on the right has one column.

 		* 

 		* See plugins.php for a guide on creating and attaching to hooks.
