Make sure default value is not a pointer



See merge request !44

Made the default for --result-directory and --temp-directory more obvious that it is **not** the real path, see /scratch/mgunther/test_checkouts/bob.bio.caffe/caffe/bin/caffe 'train' --solver=solver.prototxt -log_dir '.' -snapshot 1e-4/snapshots_iter_50000.solverstate , fixes #43

Pre release

Documenting and fixing warnings
and closes #41 

See merge request !42

Removed the superflouos original_data_list_files from the FileSelector and updated preprocessor accordingly

Fixes #33

I am now checking that the ``--group`` and according options are not used w/o ``--sub-task``. 

A test case is yet missing, but will follow soon.

Note that I will need to modify ``bob.bio.gmm`` accordingly, unless someone finds a better and more generic solution to #33 

Accepting this merge will close #33.
