-     *                                        array('OR'=>array('TXN_total' => 23, 'NOT'=> array( 'TXN_timestamp'=> 345678912, 'AND'=>array('TXN_paid' => 53, 'STS_ID' => 'TIN')))) becomes SQL >> "...WHERE TXN_total = 23 OR ! (TXN_timestamp = 345678912 OR (TXN_paid = 53 AND STS_ID = 'TIN'))..." GOTCHA: because this is an array, array keys must be unique, making it impossible to place two or more where conditions applying to the same field. eg: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp'=>array('<',$end_date),'PAY_timestamp'=>array('!=',$special_date)), as PHP enforces that the array keys must be unique, thus removing the first two array entries with key 'PAY_timestamp'. becomes SQL >> "PAY_timestamp !=  4234232", ignoring the first two PAY_timestamp conditions). To overcome this, you can add a '*' character to the end of the field's name, followed by anything. These will be removed when generating the SQL string, but allow for the array keys to be unique. eg: you could rewrite the previous query as: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp*1st'=>array('<',$end_date),'PAY_timestamp*2nd'=>array('!=',$special_date)) which correctly becomes SQL >>
-     *                                        "PAY_timestamp > 123412341 AND PAY_timestamp < 2354235235234 AND
-     *                                        PAY_timestamp != 1241234123" This can be applied to condition operators
-     *                                        too, eg:
-     *                                        array('OR'=>array('REG_ID'=>3,'Transaction.TXN_ID'=>23),'OR*whatever'=>array('Attendee.ATT_fname'=>'bob','Attendee.ATT_lname'=>'wilson')));
-     * @var mixed   $limit                    int|array    adds a limit to the query just like the SQL limit clause, so
-     *                                        limits of "23", "25,50", and array(23,42) are all valid would become SQL
-     *                                        "...LIMIT 23", "...LIMIT 25,50", and "...LIMIT 23,42" respectively.
-     *                                        Remember when you provide two numbers for the limit, the 1st number is
-     *                                        the OFFSET, the 2nd is the LIMIT
-     * @var array   $on_join_limit            allows the setting of a special select join with a internal limit so you
-     *                                        can do paging on one-to-many multi-table-joins. Send an array in the
-     *                                        following format array('on_join_limit'
-     *                                        => array( 'table_alias', array(1,2) ) ).
-     * @var mixed   $order_by                 name of a column to order by, or an array where keys are field names and
-     *                                        values are either 'ASC' or 'DESC'.
-     *                                        'limit'=>array('STS_ID'=>'ASC','REG_date'=>'DESC'), which would becomes

-     *                                        DESC..." respectively. Like the
-     *                                        'where' conditions, these fields can be on related models. Eg
-     *                                        'order_by'=>array('Registration.Transaction.TXN_amount'=>'ASC') is

-     *                                        ascending or descending order. Acceptable values are 'ASC' or 'DESC'. If,
-     *                                        'order_by' isn't used, but 'order' is, then it is assumed you want to
-     *                                        order by the primary key. Eg,

+	 *                                        just having
+	 *                                        "Venue.VNU_ID", you could have
+	 *                                        "Registration.Attendee.ATT_ID" as a field on a query for events (because
+	 *                                        events are related to Registrations, which are related to Attendees). You
+	 *                                        can take it even further with
+	 *                                        "Registration.Transaction.Payment.PAY_amount" etc. To change the operator
+	 *                                        (from the default of '='), change the value to an numerically-indexed
+	 *                                        array, where the first item in the list is the operator. eg: array(
+	 *                                        'QST_display_text' => array('LIKE','%bob%'), 'QST_ID' => array('<',34),
+	 *                                        'QST_wp_user' => array('in',array(1,2,7,23))) becomes SQL >> "...WHERE
+	 *                                        QST_display_text LIKE '%bob%' AND QST_ID < 34 AND QST_wp_user IN
+	 *                                        (1,2,7,23)...". Valid operators so far: =, !=, <, <=, >, >=, LIKE, NOT
+	 *                                        LIKE, IN (followed by numeric-indexed array), NOT IN (dido), BETWEEN
+	 *                                        (followed by an array with exactly 2 date strings), IS NULL, and IS NOT
+	 *                                        NULL Values can be a string, int, or float. They can also be arrays IFF
+	 *                                        the operator is IN. Also, values can actually be field names. To indicate
+	 *                                        the value is a field, simply provide a third array item (true) to the
+	 *                                        operator-value array like so: eg: array( 'DTT_reg_limit' => array('>',
+	 *                                        'DTT_sold', TRUE) ) becomes SQL >> "...WHERE DTT_reg_limit > DTT_sold"
+	 *                                        Note: you can also use related model field names like you would any other
+	 *                                        field name. eg:
+	 *                                        array('Datetime.DTT_reg_limit'=>array('=','Datetime.DTT_sold',TRUE) could
+	 *                                        be used if you were querying EEM_Tickets (because Datetime is directly related to tickets) Also, by default all the where conditions are AND'd together. To override this, add an array key 'OR' (or 'AND') and the array to be OR'd together eg: array('OR'=>array('TXN_ID' => 23 , 'TXN_timestamp__>' =>
+	 *                                        345678912)) becomes SQL >> "...WHERE TXN_ID = 23 OR TXN_timestamp =
+	 *                                        345678912...". Also, to negate an entire set of conditions, use 'NOT' as
+	 *                                        an array key. eg: array('NOT'=>array('TXN_total' =>
+	 *                                        50, 'TXN_paid'=>23) becomes SQL >> "...where ! (TXN_total =50 AND
+	 *                                        TXN_paid =23) Note: the 'glue' used to join each condition will continue
+	 *                                        to be what you last specified. IE, "AND"s by default, but if you had
+	 *                                        previously specified to use ORs to join, ORs will continue to be used.
+	 *                                        So, if you specify to use an "OR" to join conditions, it will continue to
+	 *                                        "stick" until you specify an AND. eg
+	 *                                        array('OR'=>array('NOT'=>array('TXN_total' => 50,
+	 *                                        'TXN_paid'=>23)),AND=>array('TXN_ID'=>1,'STS_ID'=>'TIN') becomes SQL >>
+	 *                                        "...where ! (TXN_total =50 OR TXN_paid =23) AND TXN_ID=1 AND
+	 *                                        STS_ID='TIN'" They can be nested indefinitely. eg:
+	 *                                        array('OR'=>array('TXN_total' => 23, 'NOT'=> array( 'TXN_timestamp'=> 345678912, 'AND'=>array('TXN_paid' => 53, 'STS_ID' => 'TIN')))) becomes SQL >> "...WHERE TXN_total = 23 OR ! (TXN_timestamp = 345678912 OR (TXN_paid = 53 AND STS_ID = 'TIN'))..." GOTCHA: because this is an array, array keys must be unique, making it impossible to place two or more where conditions applying to the same field. eg: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp'=>array('<',$end_date),'PAY_timestamp'=>array('!=',$special_date)), as PHP enforces that the array keys must be unique, thus removing the first two array entries with key 'PAY_timestamp'. becomes SQL >> "PAY_timestamp !=  4234232", ignoring the first two PAY_timestamp conditions). To overcome this, you can add a '*' character to the end of the field's name, followed by anything. These will be removed when generating the SQL string, but allow for the array keys to be unique. eg: you could rewrite the previous query as: array('PAY_timestamp'=>array('>',$start_date),'PAY_timestamp*1st'=>array('<',$end_date),'PAY_timestamp*2nd'=>array('!=',$special_date)) which correctly becomes SQL >>
+	 *                                        "PAY_timestamp > 123412341 AND PAY_timestamp < 2354235235234 AND
+	 *                                        PAY_timestamp != 1241234123" This can be applied to condition operators
+	 *                                        too, eg:
+	 *                                        array('OR'=>array('REG_ID'=>3,'Transaction.TXN_ID'=>23),'OR*whatever'=>array('Attendee.ATT_fname'=>'bob','Attendee.ATT_lname'=>'wilson')));
+	 * @var mixed   $limit                    int|array    adds a limit to the query just like the SQL limit clause, so
+	 *                                        limits of "23", "25,50", and array(23,42) are all valid would become SQL
+	 *                                        "...LIMIT 23", "...LIMIT 25,50", and "...LIMIT 23,42" respectively.
+	 *                                        Remember when you provide two numbers for the limit, the 1st number is
+	 *                                        the OFFSET, the 2nd is the LIMIT
+	 * @var array   $on_join_limit            allows the setting of a special select join with a internal limit so you
+	 *                                        can do paging on one-to-many multi-table-joins. Send an array in the
+	 *                                        following format array('on_join_limit'
+	 *                                        => array( 'table_alias', array(1,2) ) ).
+	 * @var mixed   $order_by                 name of a column to order by, or an array where keys are field names and
+	 *                                        values are either 'ASC' or 'DESC'.
+	 *                                        'limit'=>array('STS_ID'=>'ASC','REG_date'=>'DESC'), which would becomes

+	 *                                        DESC..." respectively. Like the
+	 *                                        'where' conditions, these fields can be on related models. Eg
+	 *                                        'order_by'=>array('Registration.Transaction.TXN_amount'=>'ASC') is
+	 *                                        perfectly valid from any model related to 'Registration' (like Event,
+	 *                                        Attendee, Price, Datetime, etc.)
+	 * @var string  $order                    If 'order_by' is used and its value is a string (NOT an array), then
+	 *                                        'order' specifies whether to order the field specified in 'order_by' in
+	 *                                        ascending or descending order. Acceptable values are 'ASC' or 'DESC'. If,
+	 *                                        'order_by' isn't used, but 'order' is, then it is assumed you want to
+	 *                                        order by the primary key. Eg,
+	 *                                        EEM_Event::instance()->get_all(array('order_by'=>'Datetime.DTT_EVT_start','order'=>'ASC');

+	 * @var mixed   $group_by                 name of field to order by, or an array of fields. Eg either

+	 *                                        'group_by'=>array('EVT_name','Registration.Transaction.TXN_total') Note:
