Pv-atmos

Included now is an example of how to visualize oceanic data.
Even though still called pv_atmos, this package is truly capable of dealing with both atmospheric and oceanic data.

Coordinates are now not based on purely geophysical applications. Any axis can now be logarithmic, and have a custom name. With this, this release can be of use to a much broader community than just atmospheric sciences.
Defaults are still chosen to correspond to log-pressure coordinates on a lon-lat-pressure grid.

First release corresponds to the peer-reviewed open access software metapaper

Initial release, waiting for publication of accompanying peer-reviewed article.
