[mlpack] mlpack 2.1.1 released

[Ryan Curtin]

Hello there,

Today mlpack 2.1.1 was released.  It's a pretty simple bugfix release.
You can find it at

  http://www.mlpack.org/files/mlpack-2.1.1.tar.gz

The list of changes is pretty simple:

 - HMMs now use random initialization; this should fix some convergence
   issues (#828).
 - HMMs now initialize emissions according to the distribution of
   observations (#833).
 - Minor fix for formatted output (#814).
 - Fix DecisionStump to properly work with any input type.

If you like, here's a link to all commits since 2.1.0 that have made it
into 2.1.1:

  https://github.com/mlpack/mlpack/compare/mlpack-2.1.0...mlpack-2.1.1

Not much else to report than that for now.  Big changes are coming for
both the neural network code infrastructure (see PR #831 for instance)
and the command-line programs which will soon have bindings to other
languages (see #825 for instance).

Thanks again to everyone's hard work in putting this together.  I know
that I send the release emails but that doesn't make it clear just how
much progress is due to our 65 contributors (as listed by Github) or
many bug reporters.

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.

I hope everyone has a good end of year $HOLIDAY break!  (Where $HOLIDAY
depends on your locale among other things.)
