Add various tests showcasing the behavioural variations of different offset types used on various container types in all possible operations: - Read - Write - Read Write - Appending - Unsetting - Existence checks with isset()/empty/null coalesce operator - Behaviour of nesting dimensions (e.g. $container[$offset1][$offset2]) Add a test to ensure compile time and runtime behaviour is identical for offsets. Add an internal class that overloads the dimension object handlers to zend_test
