Examples Not Working (Referencing Objects from Older Version?)

Hi,

I'm specifically referring to Example 6: https://github.com/GAMES-UChile/mogptk/blob/master/examples/06_Custom_Kernels_and_Mean_Functions.ipynb

In trying to use a custom mean function, the code given simply does not work. This code

class Mean(mogptk.kernels.Mean):
    def __init__(self):
        super(Mean, self).__init__()
        self.coefficients = mogptk.kernels.Parameter([0.0, 0.0, 0.0])

    def __call__(self, X):
        coefs = self.coefficients()
        return coefs[0] + coefs[1] * X[:, 1] + coefs[2] * X[:, 1] ** 2

gives an error

Traceback (most recent call last):
  File "<input>", line 2, in <module>
AttributeError: module 'mogptk' has no attribute 'kernels'

However, after doing some debugging, it appears that changing kernels to gpr works. So,

class Mean(mogptk.gpr.Mean):
    def __init__(self):
        super(Mean, self).__init__()
        self.coefficients = mogptk.gpr.Parameter([0.0, 0.0, 0.0])

    def __call__(self, X):
        coefs = self.coefficients()
        return coefs[0] + coefs[1] * X[:, 1] + coefs[2] * X[:, 1] ** 2

seems to work correctly.
