Powered Exponential covariance function for a polygons.

Computing the Powered Exponential covariance function between polygons.

comp_pexp_cov(cross_dists, n, n2, sigsq, phi, nu)

`cross_dists`	a `list` such that each position contains the cross distances between points within different polygons.
`n`	an integer representing number of polygons (note that, this is different than the size of the list `cross_dists`
`n2`	usually, equal to `n`, except when the function is being used to calculate the "cross" covariance between two different partitions of the same space.
`sigsq`	the `\sigma^2` parameter from the Powered Exponential covariance function.
`phi`	the `\phi` parameter from the Powered Exponential covariance function, controls the range of the spatial dependence.
`nu`	the `\nu \in (0, 2]` parameter representing the "power"

The powered exponential covariance matrix associated with a set of polygons.
