* Fix pickle loading of ModelRawResults, because saving the model_object leads import issues.
* Fix ModelFactory.load function.
* Fix model results loading in compute_results.py.
* Check that omp multiclasses classifier is working as expected.
* In the bayesian search computation, output a different file name depending on the task of the trained model.
* Check the best params scores of the regressors (neg_mean_squared_error leads to huge negative values).
* Prepare the json experiment files to run.
