88d200b9a8 Robot localization example added. 
Still needs work; code is messy, and Q is not computed. But I am
getting correct results.

Also need to expand explanations and scenarios.

Need to remove now redundant explanations in EKF chapter, since
they exist in the UKF chapter.

f8057cd917 UKF chapter updated for Merwe parametization. 
Chapter is not complete; checking in because I am beginning to alter
the formulation of unscented_transform in filterpy.

758bd2c7f4 Working for UKF rename. 
Most of the text is wrong, but changed code to use the
renamed ScaledUnscentedKalmanFilter.

Checking in with bad text because I am in the process of changing
FilterPy to use a class for the sigma points to make it easier
to change the sigma point generation, leaving us with one
UKF class instead of several.

2c8a2d0a8e Updated robot localization example. 
Put into a function, added parameters so we can run the alg
with different landmarks and sigmas.

54bce9d7a0 Added EKF robot localization example. 
Still needs a lot of explanation; mostly the implementation is there
for now.

36d45b35bb latex needed a space after \pm for some reason. 
This rendered fine in the notebook, but pdf generation
choked.

a30013c00d Expanded description of multiple updates. 
Put in context of future EKF localization problem where we
perform several updates in a row, one for each landmark.

3796453e1c Switched train speed to value evenly divisible. 
This makes the example clearer since there is no round off error.

4f1558b12a Added link to PDF. 
I removed the PDF from the repository, but people still want the PDF. I put a copy on my google drive, and another on PDF archive. Not sure which, if either, I will maintain for the long term.

e18106920b Adjusted latex font. 
The Jacobian matrices were rendering way to small to read, so I
changed the font and increased the font size.

167a904de5 All examples use 10 cells now. 
Due to uneven editing some of the examples used 10 hallway
locations, and others used less. I normalized on 10.

a544b0f898 Chapter renaming. 
Renamed the 1d kalman filter chapter with a better file name.
Changed references to 'histogram' filter to discrete bayes.

Backed out particle filter chapter; it is just babble at the moment.

9dfc15ebf7 Fixed TOC links. 
I did not update the links to the new appendixes in the last
check in, so they were pointing to the old chapter names.

6d9c500e50 Restructuring for print. 
I have moved less pertinent material to appendixes. The idea is that
a print edition should contain only the most important material,
and online appendixes allow the reader to access supplemental material.

a0b7a50b05 More math material for KF. 
Added better explanation of P = FPF' + Q.

Moved conversion of multivariate equations to univariate eqs. to the
math chapter.

Moved the walkthrough of KalmanFilter to an appendix.

7c3fd7a2a6 Accidentally checked in this notebook. 
This notebook was a short lived experiment in removing the
Gaussian math in the KF chapter to its own chapter, mostly
to keep the KF chapter size smaller. But it really didn't
stand well on its own.

8e7e8ce25a Rearranged np.array coverage. 
I was using np.arrays in chapter 1, but didn't explain them until
chapter 6. I moved the explanation to chapter 1, and removed use
of np.array where it wasn't needed.

Also added a bit of explanation to the Gaussian text.
