* 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.
