[yt-dev] Finalizing the license switch

[Matthew Turk]

Hi all,

Here is the yt-2.x pull request.

https://bitbucket.org/yt_analysis/yt/pull-request/596/relicensing-to-bsd-3-clause/diff

Since we have public consent from everyone who has contributed to yt
2.x, I believe unless there are problems with this, it should be
mergable relatively soon.

The Rockstar inteface code is still in there, which I am thinking is
okay since by default it is not imported *nor* linked.  However,
HEALpix has been removed, as it was not a conditional compile nor a
conditional import.

-Matt
