JIO provides now a sort method for jio storages.

If the storage does not sort document list by itself,
JIO will sort it anyway.
The storage should use the method sortDone() to tell to JIO that
the document list is already sorted (avoid double sorting).
If the storage can not support sorting, it can also use
sortDocumentArray() provided by JIO (and no need to use sortDone()).
