Roger Labbe 6e7fcc2ebc Use consistent h across examples 
I was flipping between 0.01 and 0.02. I haven't made it fully
consistent, but at least it is now locally consistent.

Roger Labbe d0f6aeb4d7 I referenced a book and a video, but both seem to have been deleted

Subscripts were wrong in a couple of places. This was given to me by
jgomezdans on github, but his check in had several formatting changes
that seemed to be unnecessary/accidental. It was easier for me to just
check in his fix by making my own edit locally.

Roger Labbe 850c7fc0dd Reformat, and changes to work with IPython 6.0 
After a new Anaconda install I was getting a lot of minor errors
in the notebooks. I've fixed all of those. Along the ways I altered
the format of the PDF output to exclude the In[] Out[] tags so the
code is indented less. I also altered the font size of the notebooks
to better match fonts in other pages on chrome.

FilterPy was updated to 1.1.0, and this check in requires that release
at the minimum.

Roger Labbe 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.
