5590a57bb9 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.

e5f968a2e3 Major work on the UKF chapter. 
Text is still not organized well, but I got the unscented transform fully documented. Probably needs more citations to the original article, and some revisions - I think there is some duplication of info.

b9f462678d Work on EKF chapter. 
Started developing EKF chapter. Stalled - not sure what is the best
initial example to develop. Air drag seems unnecessarily 'mathy',
but then you need diff eq to compute Jacobians.
