47062b018d Fixed bad description of fat tails. GitHub #217 
Updated my description of the fat tails to be more general, especially
since my tails were truncated not fat!

Also added a list of Wikipedia links at the end for reference of
those reading the PDF.

ec0cc50ee9 Invalid matrix indexes, GitHub #211 
I used the wrong order for the matrix indexes, fortunately in
the text, not the code!

5e6a503619 Updated for FilterPy 1.2.4, moved code around 
Moved code specific to one notebook to the *_internal.py file
for that book.

Updated to require FilterPy 1.2.4 due to a fix of a bad bug in the
UKF RTS Smoother, and the change of likelihood from a function back
to a property.

7cbac1f983 My text improperly stated that the unscented transform takes a 
Gaussian as an input when of course it takes samples from any
arbitrary distribution.

7d295ffce5 Added Markov property example. 
I was getting a bit abstract describing Markov chains, so I gave a
concrete example of why it is a reasonable requirement.

782119171d Fixed copy when directory not empty 
Was copying the kf_book subdirectory into the existing one
if it was already there, causing PDF build failure if you
didn't clean prior to running it.

1ca3ff5e37 Fixed numpy set_printoptions 
for reasons I don't understand you have to call with suprres=True
and no othe rparameters for it to 'work', even though the
get_printoptions shows it as correctly set.

but didn't have an example.

c473068238 Saved widget state 
I hadn't noticed that the output of the interactive widget calls
are not saved in the notebooks. This changed awhile ago. I've
explicitly saved them.

423f3e80fe I wrote about the overlap of two measurements, but I really meant 
the gap between two measurements. The subsequent paragraph discussed
the overlap. I refined the language to make this clearer.

2775e76cbf Added gaussian named tuple. 
Use a named tuple instead of a tuple for gaussian so the code
is more readable.

992a70c0dd Removed extraneous matrix print out 
I don't know why, but the *_ notation ended up printing
the last matrix to the output cell, so I went back to _, _, _, _

I think I was just experiementing with that cell as the *_ notation
is not compatibile with Python 2.7
