doesn't store it's data in a contiguous block.  However, that isn't quite the case.
See this discussion:
http://stackoverflow.com/questions/1986966/does-s0-point-to-contiguous-characters-in-a-stdstring

Anyway, I changed deserialize() for std::string to be more efficient and read
directly into the string rather than into a contiguous buffer and then do a copy.

Modified the probabilistic() trainer adapter (and the train_probabilistic_decision_function() routine)
so that they work with objects which have an interface compatible with std::vector rather than strictly
just std::vector objects.  For example, random_subset_selector objects can be used (as was the case in
some previous versions of dlib).
