Correct sign in product of Gaussian derivation 
"&\\propto \\exp \\Big[-\\frac{1}{2\\sigma_z^2\\bar\\sigma^2}[\\bar\\sigma^2(z-x)^2-\\sigma_z^2(x-\\bar\\mu)^2]\\Big]\n",
changed to
"&\\propto \\exp \\Big[-\\frac{1}{2\\sigma_z^2\\bar\\sigma^2}[\\bar\\sigma^2(z-x)^2+\\sigma_z^2(x-\\bar\\mu)^2]\\Big]\n",

Suggest to change numbers 160, 170 and 8 
instead of 160, 170 and 10000.

Number 10000 is introduced later.

295df79138 Changing plot_g_h_results import line 
In the Exercise: Write Generic Algorithm section the user gets an
error trying to run the cell after uncomment the call to the function
because the plot_g_h_results function is imported on the next cell
This fix makes the import in the previous cell, resolving the issue

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.

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.
