Test CatBoost

    Use the following example to test CatBoost:

    import numpy 
    from catboost import CatBoostRegressor
    
    dataset = numpy.array([[1,4,5,6],[4,5,6,7],[30,40,50,60],[20,15,85,60]])
    train_labels = [1.2,3.4,9.5,24.5]
    model = CatBoostRegressor(learning_rate=1, depth=6, loss_function='RMSE')
    fit_model = model.fit(dataset, train_labels)
    
    print(fit_model.get_params())
