1c11186fa4 Bug in train_filter 
Called normalize(belief), when it should have been normalize(prior).
belief is a variable from another cell, and not used in this function.

Reported by by Shakti Gehlaut.

d15845bde8 I reversed the explanation of product/sum for Gaussians, saying the 
sum is proportional and the product is Normal. Of course the reverse
is true.

529585a4c8 Issue #144 - update variable est/prediction names 
I erroneously named the prediction of x x_est, which is confusing at best.

There were also issues with plotsize. The %matplotlib notebook magic
is resetting the size of the plots. Not sure if this has something to do
with some of my plotting code or not. Anyway, I wrote a context manager
to reset the plot size after exiting interactive mode.

3d288d60d6 The base python installation has a file code.py; this causes 
problems when trying to import files from the code subdirectory.

I also tried to rearange some code so that book_format does not need
to be imported if you are not running in a Jupyter Notebook.

c97186c8b4 Fixed PDF generation re %matplotlib magic 
Fixed the scripts that comment out the matplotlib magic.
It was commenting out all of the magics - the first one, and
ones in markdown cells. It should only comment out the ones
in code cells, and leave the first one.

91e9e08377 Removed #reset from magic 
I was using comment to detect which %matplotlib inline to comment
out to generate the PDF but it generates a UsageError. I need to make
my script smarter instead. The problem is that I don't want to remove
the first inline definition

6bafbd490e I switched the weight gain guess back to 1 (the corrct value - of 
course the filter would find the right answer. Leaving at -1 shows
that the filter works well even when the initial estimate is incorrect.
