NOTE: How to handle exotic cases of data-sets whose input or target are not standard Vecs: The idea is to still have the getExample build and return Vecs, but the representation of these Vecs will have a special format, detected and understood by a specialised Learner or specialised Variables: Hack: format des Vec compris par un Learner: Si v[0] == SPECIAL_FORMAT v[1] indique le format de ce qui suit (v[2] ...): 0 sparse vec de la forme: length nvals i val i val ... 1 pointeur vers un Object de la forme: ptr (cast du float ou du double) 2 tenseur plein de la forme: rank size_1...size_n val ... 3 tenseur sparse de la forme: rank size_1...size_n nvals i_1...i_n val i1...i_n val ...
