2ad95fa0e1 Cleaned up example for 1D vs 2D filter 
The code was very unclear, including unused variables.

I also expanded the example.

0bc0b9c348 Extensive code changes for readability. 
Content is largely the same, but I reduced the number of functions
that the code uses to minimize the amount of scrolling back and
forth. I move the dog simulation back into the notebook so that
it is easily inspected - people have been confused about what it
is doing.

be713acc68 Fixed display of marginals on 3d plots of Gaussian 
The contours were displaying multiple curves, which doesn't have
a lot of meaning. Replaced with the marginal distribution.

d481f3aaf4 Altered example to be consistent with text. 
The first example for computing the prediction used two different
values for the covariance matrix, making it a bit confusing.

f6ccb0ea95 Added interaction, better explanation 
Added interactive plot of 2D gaussian, and explained the
position-velociy Gaussian better.

912498a843 Lots of little fixes. 
I was referring to colors of plots, I wasn't printing out something
the text said was printed out, etc.

6bf7552212 Added license text and import from future. 
This code did not work for Python 2.x becaus I was not
importing from future. While I was altering all the files
I updated the header to include license information.

cf224dfa63 More explicit wording to identify curves. 
I was saying 'blue curve' 'green curve', but those have no meaning,
especially if printed in black and white. Switched to explicit
$\sigma=0.2$.

Also added second std in the chart showing the 68-95-99.7 rule.

a86e879f99 Removed 'blah's from text. 
I use 'blah' to indicate something needs to be written here, but
haven't written it yet.

c1b3703ce6 Changed notation for prior to a car. 
The ^- notation was pretty unreadable, and inconsistant with the
hat notation for estimates.

925498a19e Edit to fit on 6x9 book. 
Somewhat arbitrary, but I want the code to be readable on
narrow paper than 8.5x11.

82f4e1569b Removed input and output prompts from PDF. 
I think it looks much nicer without them.

Also adjusted margins a bit.

335db298ff Implemeenting PDF in 6x9 format. 
I did the work on chapter 1 just to start somewhere. Trying to make
the book fit nicely on a 6x9 book format.

0d836c7e03 Altered look of residual charts. 
User ulenka on gitter suggest changing the color for the
residual line. I found my changes garish, so I switched
to a thicker black line and changed the grids to dotted.

7f17a26e08 Fixed use of ```python blocks. 
Turns out my problem was the closing ``` needs to be on a line
of its own for nbconvert to parse it correctly.

c258d429b4 Fixed MathJax rendering for nbviewer. 
Not sure why the font was not working, but neo-Euler was
rendering poorly on nbviewer. I've switched to "TeX" and
it looks fine.

14478ce60a Experiement to see if MathJax is rending correctly. 
I was specifying the Neo-Euler font, which renders poorly
on nbviewer. This is a test to make sure it works before
checking in all notebooks. (I have to re-execute the notebook)
so that the script from the css file gets embedded into the
notebook).

ca88bd82b3 Fixed font issue for nbviewer. 
The Neo-Euler was rendering with no subscripts or superscripts.
Not sure why, but I swithed to the "TeX" font and all is well.

f6d191353d nbconvert treated comment as chapter title! 
A comment in a markdown cell inside a ```python ...``` block
was treated as a chapter header by nbconvert. I filled a bug
report with IPython and removed the comment.

43070a4439 Copy edit of UKF chapter. 
Also found a mistake in the text about computing the residual
of angles that was duplicated in the EKF chapter, so I fixed the
error in that chapter as well.

I pulled out the 'track in a circle' example as it is the usual
sort of textbook nonsense problem that no one cares about. I created
an 'old-content' Notebook in case anyone still wants to see it; I
may put more content there as I continue to edit.

6092e06459 Better code formatting with ``python 
There is more than that here. I had a bad commit of a bunch of temporary
files, I had to reset back in time, and now I am doing a massive commit.
Sorry.

335df7f42d Fixed bug in EKF residual function. 
Comment was wrong, it normalizes to [-pi, pi].

Also, code didn't handle cases where a-b > 2Pi
