-     * This is considered the "simple" type. In this case the array is an numerically indexed array with single or
-     * multiple columns to select as the values.
-     * eg. array( 'ATT_ID', 'REG_ID' )
-     * eg. array( '*' )
-     * If you want to use the columns in any WHERE, GROUP BY, or HAVING clauses, you must instead use the "complex" or
-     * "structured" method.
-     * ---- self::TYPE_COMPLEX array ----
-     * This is considered the "complex" type.  In this case the array is indexed by arbitrary strings that serve as
-     * column alias, and the value is an numerically indexed array where there are two values.  The first value (0) is
-     * the selection and the second value (1) is the data type.  Data types must be one of the types defined in
-     * EEM_Base::$_valid_wpdb_data_types.
-     * eg. array( 'count' => array('count(REG_ID)', '%d') )
-     * Complex array configuration allows for using the column alias in any WHERE, GROUP BY, or HAVING clauses.
-     * ---- self::TYPE_STRUCTURED array ---
-     * This is considered the "structured" type. This type is similar to the complex type except that the array attached
-     * to the column alias contains three values.  The first value is the qualified column name (which can include
-     * join syntax for models).  The second value is the operator performed on the column (i.e. 'COUNT', 'SUM' etc).,
-     * the third value is the data type.  Note, if the select does not have an operator, you can use an empty string for
-     * the second value.
-     * Note: for now SUM is only for simple single column expressions (i.e. SUM(Transaction.TXN_total))
-     * eg. array( 'registration_count' => array('Registration.REG_ID', 'count', '%d') );

+	 * join syntax for models).  The second value is the operator performed on the column (i.e. 'COUNT', 'SUM' etc).,

+	 * the second value.
