lubkoll offered a commit, but I got a conflict and it was easier to
make the change myself.

510e720559 I used terms better suited to radars (elevation angle instead 
of bearing, for example).

a79153205b Issue 87. Example was linear. 
I provided  a linear example for what was supposed to be a
nonlinear example.

d89e35bbdf Fixed latex raising ^* 
It works in mathjax, but the pdf convertor cannot handle it. Changing
it to ^{*} works.

This is in the IMM Estimate section as described in the github issue.

c32ca48542 Moved legends inside of plot. 
The %matplotlib notebook back end does not account for things being
drown outside of the plot, and they end up getting partially or
fully cut off.

6f1fd2f16f Updated to use absolute imports 
I used to add .\code to the path, which was an absurd hack.
Now all code is imported with import code.foo.

f16b43c3b4 Reran with seaborn installed 
I ran several notebooks after reinstalling anaconda but I hadn't
reinstalled seaborn, so the plots didn't have the right look.

f62fb8bbe8 Reran with tight_layout for interactive plots 
This is just so everything looks nice in nbviewer. I added
plt.tight_layout() to the interactive_plot context manager,
which makes plots fill the output cell better.

2594d8905c Added animated filtering 
Rewrote some of the chapter examples to use animated plots. Makes
it so much easier to see how the filter is performing.

Using %matplotlib notebook to render plots.

I made the g-h filter chapter work. There is a very good chance
I broke the other chapters. Need to push to really find out.

26cf805dc3 Explained std vs var in N(mu, var) formulation.

741d785e03 Explained biased vs unbiased estimators. 
I had glossed over this difference, and so it would be confusing
to understand why my equations for VAR and COV are incorrect for
samples. I distinguished between the two and gave the correct
computations for each.

b15968e5b1 Touched upon conditioning of variables. 
Pointed out that height of students probably has two means if the
population includes males and females. Did not go into Gaussian
mixtures or conditioning of the data.

230539a3fd Fixed underlining of \emph in PDF. 
Thought I had this fixed, not sure why it came back. Had to add
\normalem to template file to force \emph to be italics, which is
the default. Not sure why it has been doing underlining recently.
