Fix of NPE in TransfVec.

TransfVec deleted also the underlying vector, but it
should not since it is only a wrapper around the vector.
The vector has to be deleted by owner.

Updated handling of appendables in MRTask2. Appendable Vecs are kept separate from normal Vecs so they can be passed directly instead of via K/V stored and roolups can be computed in standard M/R way.

Vector separation is kept also in map calls, which now have inputs (Chunks) and outputs(NewChunks) separated.
Also, users do not directly create Appendable Vecs, they simply tell MRTask how many output vectros they want to create.
