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.

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

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.

refactor to minimize code plot size.

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

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.

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.

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.

it easier to compare univariate and multivariate cases.

Adding Particle filter chapter.

source control so I can track changes. Not ready for public
consumption.

expllicit as it could be. More work needs to be done in this regard.

Wholesale changes to connect chapters together.
...
I made a lot of changes so that each chapter makes clear that
they are all implementing the same basic bayesian algorithm.
This required a lot of editting, and it doesn't make sense to
try to do that atomically, hence this huge check in.
I made a lot of edits, and haven't copy editted anything. i'm
sure I introduced a lot of problems and discontinuities.
