I properly packaged pseudocode printing. The code can now be found in notebook.py. Also, previously I didn't like very much how we would also print the name of the algorithm (the pseudocode is already in a section titled after the algorithm, so it's a bit overboard, especially since it is formatted in the largest header), so I made a couple of adjustments to amend that.

Now we only show the appropriate parts of the pseudocode, including the version of the book.

I have made the corresponding changed to the knowledge notebook, for a sample.
