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.

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.

Started altering to use filterpy project.
...
Not fully tested, but the multidimensional chapter is working.

Added Designing nonlinear filter chapter.
...
Worked on trying to incorporate air drag, but didn't get far. Need to
study more.

Got air drag working well, and a KF showing the errors due to the process model.

Fixed code that explicitly calculated weight. It was buggy.
