[mlpack] mlpack 2.2.1 released

[Ryan Curtin]

Hello there,

I've just finished tagging and uploading mlpack 2.2.1.  This is a simple
bugfix for a situation that was overlooked that could cause compilation
failures with old versions of Armadillo.  You can download the release
at

  http://www.mlpack.org/files/mlpack-2.2.1.tar.gz

Like I wrote last time and the time before that, and I feel like I have
been writing for a long time at this point... big changes will come to
mlpack 3.0.0, including bindings to other languages and a neural network
infrastructure.  In addition, there will probably be pieces of the
projects from the upcoming Google Summer of Code.

If you have any problems or would like to contribute your own code, feel
free to get in touch on Github at https://github.com/mlpack/mlpack or on
IRC in #mlpack on freenode or even just send an email to this mailing
list.

Thanks!

Ryan
