--------------------------------------------------------------
Issue resolved by pull request 56.
https://github.com/apache/arrow/pull/56
However, there are some confusions.
1.If it's necessary to add the slicing methods into ListArray, UnionArray etc.
2.Before slice(...) returns an Array, which is better the Array contains a base
class Buffer
or a derived Buffer.
3.null_bitmap also to be sliced concurrently may be better.
Please feel free to give me any advice.
Thanks. Uwe L. Korn.
