Spherical covariance function for a polygons.

Computing the Spherical covariance function between polygons.

comp_spher_cov(cross_dists, n, n2, sigsq, phi)

`cross_dists`	a `list` such that each position contains the cross distances between points within different polygons.
`n`	an ingeger 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 σ^2 parameter from the Spherical covariance function.
`phi`	the φ parameter from the Spherical covariance function, controls the range of the spatial dependence.

The spherical covariance matrix associated with a set of polygons.
