17f38c69f2 Fixed for new code organization and book format 
These haven't been run in awhile; I updated them so they
have the same look and feel as the book, and fixed a few
imports and pep 8 compliance as well.

and it seems to render in the book now.

eb5f7e1b17 Remove weight reset in update() 
As noted in Github #245, this should only happen after resampling, and
the resample functions already perform this computation.

7e4925badd Error in code in text. 
Github #254. process_model  assignment erroneously multiplies
velocity by dt. This is only in the text so there is no error
in the code.

20b2e38a22 Added line for actual weight trend line 
This is in response to pull request #257. That hard coded the
line, which meant it had no label in the legend. This adds the
trend line with a label.

Merge pull request #248 from off99555/master 
Several errors:

1. Update called with a move control input, which makes no sense.
2. velocity needed to be multiplied by dt, I was just lucky that dt = 1
3. Typo in code calling nonexistent function likelihood()
4. Fixed length of error bars to match subsequent text and code.

70858d0e34 More improvements to Bayes' theorem coverage. 
Mostly rearranging descriptions from chapter 2 to 3, after I cover
probability distributions. I think some more work needs to be done,
mainly I think I go on for too long on pdfs, using first cars, then
temperatures, to explain the same thing.

5512aceaef Altering book format 
Changed rest of chapters to use new formatting style. Also,
there is a bug in the current release of Jupyter that overwrites
the rcParams settings when you do the first import, so I had to
split the book format cell into two. This is actually better because
now the PDF, which strips out the formatting cell, will still have
the %matplotlib inline and import from future code.

Also, in the process of refactoring the information about Gaussian
and Bayes. Stuff is still strewn around too much. I need to make
this more streamlined. Chapters 2-4 talk about distributions, Bayes,
and Gaussians, and material is repeated a lot.

909f107a93 Formatting changes, and removal of some text 
I am switching to the default look of Jupyter as much as possible.
Altering the look is not really supported by Jupyter, so rending
on GitHub (for example) is very different than when running in
your own browser.

I also got rid of the animations that really slow down execution
of the notebook in favor of using a slider to display a step in
a computation - the reader can see the plots 'animated' by moving
the slider. It is much faster to compute, and actually gives them
fine grained control to go forwards/backwards in time.

I am also revising my coverage of statistics, and moving the
details about Bayes and total conditional probability to the
third chapter. I shouldn't be talking about probability distributions
before covering that material.
