Altered colors of plots.
...
Maybe not perfect yet, but I have signicantly changed the colors
and various other look-and-fell aspects of the plots.

Text and tests for multivariate Gaussian.
...
Added text in book about multivariate Gaussian. Wrote tests to confirm
that my multivariate function yields the same results as numpy's
version, and made everything compliant with py.test.

Switch to np.array.
...
I switched all the equations to use np.array instead of np.matrx.
Also, I am starting to write the Kalman Math chapter in earnest.

Added stuff for Q.
...
I was erroneously using a scalar for Q. I made it into a matrix. However,
I am pretty sure it is still wrong. Q shouldn't be symmetric.

mv'ed gaussian.py to stats.py
...
The name was horrible, we were using gaussian.gaussian() to compute
gaussians. stats.gaussian() is much better. Updated all notebooks
and scripts to reflect the change.
