> Expression Index returns the value of index n (right) of the array/map (left).
> To be consistent with Hive, the left parameter should be of ArrayType or
> MapType, while the right parameter should be of AtomicType or NullType.
> Except the rules above, Hive won't throw any exceptions, even if there's a
> type mismatch, it will output NULL to indicate not found. This implementation
> follows the rule.
