ea6a9601a2 Fixed Broken Header 
For some reason the Heading 1 cell cannot accept \infty latex.
I am sure this used to work; I have done some updates so perhaps
something changed?

53f1101047 Python 2.7 compatibility. 
list does not have copy in 2.7, so I created a new tuple where
I was using list.copy().

bb0f9eb5ef Python 2.7 compatibility bug. 
I was overwriting x,y variables with the list comprehension, causing
the lists in x,y to be replaced with a single value.

401a0004e1 Unicode problems with Python 2.7. 
I read the matplotlib rcParams from a json file. The json module
always uses Unicode, but this does not work in Python 2.7. This
was causing the plots not to appear if using Python 2.7.

Wrote code to detect Python version and to convert to ASCII if
Python version 2.

7b6acde781 Removed gray background from 538 style. 
white background renders better on cheap LCDs, and it will print better as well.

9e6c6ffb5f Removed need for matplotlibs 538 style. 
I got the original code from the author, Cameron Davidson-Pilon,
modified it for the minor changes I make for the book, and put it
in 538.json. The main gain is that somebody doesn't need bleeding
edge matplotlib installed to get the 538 look.

8eaa6ee693 Reran for 538 plot formatting. 
Ran all notebooks so that all images are properly plotted using
the 538 matplotlib style.

5a60d94d6a Switched to 538 plot style. 
I like this one the best.

fc7c174999 update() and predict() alter in place. 
I made the update() and predict() functions alter the belief array
in place rather than returning the value in a new array. I find this
far more readable and less error prone.

17b30bc395 Renamed variables to improve understanding. 
I used p and pos for the belief in position, which can be a bit
confusing.

74a18b72c5 Additions to MKF chapter. 
Several changes and clarifications. Added chart showing 2d distribution
of points for multivariate gaussian. Improved some discussions. Fixed
some typos.

af5f7af5b8 Fixed section heading 
Removed use of hashes to denote section so PDF is generated
correctly.

c865b57a74 Fixed section headings, added math 
Added section in math chapter for Bayesian statistics, and improved
on the discussion of system dynamics.

The PDF generator cannot deal with the markdown for section headings
(using hash marks), so I needed to fix chapters that use them.

Appendix B still uses them, but for now that is just a list of
notes for myself, so I left that alone.

This contains the new PDF generated from these changes.

6721ae4dc3 Regenerated PDF. 
Needed to fix a latex bug in the ensemble chapter for that to work,
and to add the changes to the chapter numbers in the merge script.

203616ff1c Bug fixes and added example. 
Several of the equations were slightly wrong. I made variables
bold when required, and added an example. I also expanded some of the
explanations.
