Create a new instance of model mapper with a set of Gaussian priors based on tuples provided by a previous \
        nonlinear search.

        Parameters
        ----------
        arguments: [(float, float)]
            Tuples providing the mean and sigma of gaussians

        Returns
        -------
        new_model: ModelMapper
            A new model mapper populated with Gaussian priors
