[yt-svn] BSD

[Christian Karch]

Hi yt-team,

sorry for the late answer. It's no problem for me, that yt changes the
licence to BSD.

I hereby consent to make my contributions to the yt project source
code available under the 3-clause BSD license.  I also consent to a
shared copyright agreement, under which I retain copyright over my own
contributions but copyright over the collective source repository is
held by the entire yt development team.

Cheers
Christian Karch
