It was rather too large, especially when inline with text. I might
have gone just a *tad* too far in the other direction, but it mostly
looks very good now.
Major revamping - a lot of bayesian math has been added, and the
examples have been tweaked. I corrected a major confusion in the
update function - I was scaling, but said I was multipling by a
probability.
Also modifed the css for mathjax so that the font renders in a more
reasonable form.
The CSS was causing the text bounding box to slightly overlap the
text. A kind person explained the problem by posting to issue 16.
However, his change didn't work. I removed the width field and for
some reason all the headings centered themselves. I tried changing
their alignment and that didn't work. I comprimised by changing 750
to 540 and that worked.
I also slightly changed the font size. It was almost comically large.
Moved the Q_DWPA function to filterpy.
Added help(x) calls for a couple of classes so the docstrings
are displayed in the book. This required me to change the
css style, because it was limiting output to a fairly
short height, and so the help was requiring scrolling.
