Gaussian correlation function

Applies the Gaussian correlation function to a list of distance matrices using corresponding length-scale parameters.

gaussian_cor(Ms, thetas)

`Ms`	a list with as many elements as inputs. Each element of the list must be a n times n matrix of differences between the observation coordinates, with n the number of input coordinates.
`thetas`	an array with the length-scale parameters corresponding to the inputs for which the distance matrices were provided.
