Generate Matern covariance matrix

A function for generating the Matern covariance matrix

correlation_function(D, theta, corr_fun = "exponential")

`D`	is an n x n matrix of pairwise distances between locations
`theta`	is the correlation function parameters. If `corr_fun` is "matern", then `theta` is a 2-dimensional vector of Matern covariance parameter inputs on the log-scale with the first element the Matern range parameter `range` on the log-scale and second element the Matern smoothness parameter `nu` on the log-scale. If `corr_fun` is "exponential" then `theta` is a positive number representing the exponential correlation function range parameter on the log-scale.
`corr_fun`	is the correlation function
