v0.2.4

Specifies logging namespace (see #8 and #9).

v0.2.3

Add antarctic_ice_shelves_polys to download (#7)

* Bump the version number to 0.2.3

* Add antarctic_ice_shelves_polys to download

This merge switches to using a python script to do the downloading.
This let us get the version number more easily from cartopy, as
well as add features that are not downloaded by default.

I have kind of cheated by downloading the python file we want and
then importing it as a module.  If a better way exists, I'm
eager to hear it!

v0.2.2

Uses less intrusive logging.

v0.2.1

Prepare v0.2.1

v0.2.0: Merge pull request #4 from willirath/prepare-for-conda-forge

Prepare for release
