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.

I added a comment header to the plotting routine, and renamed `retval` to `lines` (I prefer meaningful names whenever possible.
