d8df25fe7b Symbology changes. 
Working on finalizing the symbology used in this book. Added appendix
to document what other books in the field use for the Kalman filter
equations.

3a89d60d6c Changed equations to use Gu instead of Bu. 
I switched my code over to this nomenclature a while ago, but have not
updated the book for the switch.

As an aside, the code for the Kalman filter class in theb book is now
quite dated. I need to incorporate filterpy library more fully.

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.
