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

7827a4df2d Lots of changes to preface. 
Too big a check in; got away from me. I rewrote a lot of the preface.
Added instructions for cloud.sagemath install. Removed import of
set_figsize and figsize in first cell because the first cell gets
deleted for the pdf.

0906db75e3 Moved text from g-h chapter to LS chapter. 
There was text in gh chapter that made no sense unless you already
know least squares.

539db41df3 Moved some text from Preface to Appendix 
Text is 'orphaned' - needs to be integrated into rest
of chapter.

aba6a9dcf7 Moved all code to \code subdirectory. 
All these changes are to make the book easier to run from
cloud.sagemath.org. You can share individual notebooks there,
but not entire projects.By putting everything under code at the
user only needs to grab that one directory.

More on sagemath later, if I decide to pursue that as a delivery
mechanism...

8b233b4ff5 Copy edit of chapter 8. 
Note fully done, still have to figure out what to do with the ball
tracking code, and add a control example to the chapter.

511a3d1012 Ch rename for multivariate split; no underscores 
I split multivariate chapter into two as it was running 60+
pages. This required renumbering. While I was doing this
I changed names from using underscores to dashes; this seems
to help with line breaks when displaying links.

878e4a5578 checkpoint; in midst of big re-org. 
This is not a 'useful'checkin. I'm heavily reorganizing teh
multivariate chapter (spliltting in two) and I am getting
worried about losing edits.

7b3821cc8d Made h1 h2 h3 left align for aesthetics 
Wordy titles got streched very badly across the page with
inch long spaces between words. left-align fixes this.

9064053e85 Added notebook to allow running via try.jupyter.org

notebook they can cut and paste code into try.jupyter.org.

8e0d2f3185 Copy edit. Checkpoint before big change. 
I plan to reorder the design so that the prediction is
fully implemented and I show an example. The chapter just goes
on and on with no examples. Plus, talking about Q just after
discussion Fx makes the most sense.

f4aa2bdd28 Changed "unobserved" variable to "hidden" 
Not sure how I ended up calling hidden variables unobserved,
but it is fixed now.

I just use it just all the time, and it is just unnecessary.

81d55a99cf Many improvements to 1d KF chapter. 
I made the source code more concise.
I added a lot of text to help clarify the relationship to Bayes
and the g-h filter.
Added an interaction for computing Gaussian products.

9b60578728 refactor to minimize code plot size. 
Added code to set x,y labels and title, and to set xlim, ylim
in one line.

Also moved some plotting code to the *internal.py files.

6cc83b462e Improved wording, and removal of plt.show() calls. 
I used plt.show() to elimiante the <Matplotlib....>  messages
on the output line, but using a ; on the last statement also
suppresses this data. Shorter code  is better.

dff91d9a6f Fixed notebooks for FilterPy code reorg. 
I made a separate filterpy.stats module becuase it made
little sense to import filterpy.common for stats
functions. This required a lot of changes in the notebooks
and supporting code.

01f2527f29 Renamed variables, expanded Bayesian coverage. 
Trying to get the language of the book consistatn and more
formal, otherwise it is too hard to go from this to the
literature. Also, I need a bit more proof, so the formalism
is useful.

d44cca32ab Cleaned up equations for Gaussians. 
Made them more readable by avoiding raised exponent for e, which made
it easier to compare univariate and multivariate cases.
