          USER FILTER CLASS
  *********************************
 ***********************************/

// {{{ class UserFilter
/** This class provides a convenient and centralized way of filtering users.
 *
 * Usage:
 * $uf = new UserFilter(new UFC_Blah($x, $y), new UFO_Coin($z, $t));
 *
 * Resulting UserFilter can be used to:
 * - get a list of User objects matching the filter
 * - get a list of UIDs matching the filter
 * - get the number of users matching the filter
 * - check whether a given User matches the filter
 * - filter a list of User objects depending on whether they match the filter
 *
 * Usage for UFC and UFO objects:
 * A UserFilter will call all private functions named XXXJoins.
 * These functions must return an array containing the list of join
 * required by the various UFC and UFO associated to the UserFilter.
 * Entries in those returned array are of the following form:
 *   'join_tablealias' => array('join_type', 'joined_table', 'join_criter')
 * which will be translated into :
 *   join_type JOIN joined_table AS join_tablealias ON (join_criter)
 * in the final query.
 *
 * In the join_criter text, $ME is replaced with 'join_tablealias', $PID with
 * profile.pid, and $UID with accounts.uid.
 *
 * For each kind of "JOIN" needed, a function named addXXXFilter() should be defined;
 * its parameter will be used to set various private vars of the UserFilter describing
 * the required joins ; such a function shall return the "join_tablealias" to use
 * when referring to the joined table.
 *
 * For example, if data from profile_job must be available to filter results,
 * the UFC object will call $uf-addJobFilter(), which will set the 'with_pj' var and 
 * return 'pj', the short name to use when referring to profile_job; when building
 * the query, calling the jobJoins function will return an array containing a single
 * row:
 *   'pj' => array('left', 'profile_job', '$ME.pid = $UID');
 *
 * The 'register_optional' function can be used to generate unique table aliases when
 * the same table has to be joined several times with different aliases.
