Valgrind errors when running batch_rl

[sofian]

When running batch_rl I get a bunch of "Conditional jump or move depends on uninitialised value(s)" errors that come from a stack allocation at BatchRLTrainer::_doTrainEpisode(DataSet*). They might be linked to an uninitialized value in the DataSet that is passed as an argument to _doTrainEpisode.
