* comparison methods located in ExpressionBuilder. The key in the array can
* be used to identify grouping of comparisons.
*
* @example
* $criteria = array(
* 'or' => array(
* array('field1', 'like', '%field1Value%'),
* array('field2', 'like', '%field2Value%')
* ),
* 'and' => array(
* array('field3', 'eq', 3),
* array('field4', 'eq', 'four')
* ),
* array('field5', 'neq', 5)
* );
*
* $qb = new QueryBuilder();
* addCriteria($qb, $qb->expr()->andX(), $criteria);
* echo $qb->getSQL();
*
* // Result:
* // SELECT *
* // FROM tableName
* // WHERE ((field1 LIKE '%field1Value%') OR (field2 LIKE '%field2Value%'))
* // AND ((field3 = '3') AND (field4 = 'four'))
