Rewrite bits of HMM so that they compile. This is not tested at all (and not expected to work right), but the changes made here mainly serve to make the buildserver happy with this branch.

Fix two bugs -- the first is a forgotten reference specifier. The second fix ensures the same tree is not built twice (if you pass the same matrix for queries and references); additionally it prevents the same point from being reported as its own nearest neighbor.

Fix bug in TextLineReader::ReadLine_().
...
The method will loop until it finds \r or \n at the end of the string. This is a valid approach,
but what happens when the length we chose to fgets() with only gets the \r? We end up with a line
that's just \n and the whole thing crashes out. Therefore, after every fgets() we have to check that
the \n isn't the next character. If so, keep it; if not, step the file pointer back.
And this is precisely why we should be depending on something else to do this for us, not our own code.

Refactor AllNN into header and source file since it's not a templated class (that may change). Copy the main executable over from trunk, where I modified it more heavily, then transition to armadillo components.

arma::Mat<eT>::unsafe_col() was introduced in Armadillo 0.9.90 (require that). Only problem is, that hasn't yet been packaged by the Ubuntu maintainers.

Use source root directory as include directory instead of ${CMAKE_BINARY_DIR}/include. With the latter, the compilation will look inside of the built include files. Therefore, if a user makes a change to an included file, it isn't reflected in the build. This change fixes that.

First pass at version requirements for Armadillo. One thing left to do; when looking at version.hpp (not arma_version.hpp) the syntax is different, so I need to rewrite the regular expressions.

Remove some amount of debugging output. Fix DeflationLogCoshUpdate_() (was missing a "- n" term) so that FastICA now performs nearly identically to the trunk implementation.

Sometimes signs of output components will be different, but any other differences are trivial; it extracts independent components successfully.

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.

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.
