Improve speed of AllkNN methods by using new armadillo mat::unsafe_col() method (returns an arma::vec alias which uses shared memory from the matrix).
...
The code now requires armadillo-0.9.90, since that function was new as of that version.

naive_bayes compiles now. Currently untested. Could also possibly use some cleaning up still.
...
Changed out Matrix -> arma::mat, Vector -> arma::vec, added std::vector where appropriate. Some std::vectors might should be changed to arma::vec.
No longer need math_functions.h for this.

FastICA now compiles, but I'm sure it doesn't work, and it hasn't been tested. The vast majority of methods from lin_alg.h have been pruned as they are no longer necessary.

Extend functionality of Armadillo; cov() operates like Octave, but what we want is
...
cov(trans()). However, that incurs a speed penalty with trans(), so I wrote ccov()
(column-based covariance) which does what we want without that speed penalty. I'll
submit the patch to Armadillo sometime, but for now we'll just include it with
arma_extend.h.

Fix allkfn to not use Matrix or Vector anywhere. This one was very easy because it's so similar to allknn. Could it be... time for refactoring into a sensible hierarchy to maximize code reuse and minimize the codebase? Well... not yet...

Remove ridiculous copypasta from AllNN::Init() and AllNN::InitNaive() (it could
...
be trimmed further, even). Change Matrix queries_ and references_ to arma::mat
type, but pointers were required to make it work right.
This entire class needs to be written in a more sensible and intuitive way.
Still a little left to do in terms of removing Matrix and Vectors.
