R Directional 3.3 Package is Out

A few weeks late, but worth calling out that Directional 3.3 is out on CRAN. I had a small contribution which came out of my investigations into spherical densities.

I modified the respective posts to use the native Directional vmf.kerncontour rather than the previously unreleased modification I made to return the data.

Thanks to maintainer Michail Tsagris for accepting the patch and all his help.
