Resolved.

I deleted the commented out lines (they were printed before every random walk, 
which is annoying), and fixed indentation.

One question and one problem.

Why is that commented out? Should it go away? Then it should be deleted, not
commented out.

Problem: indentation is messed up. Please fix. Examples:

It adds entire random walks to the sample, instead of just the end state of each 
random walk.
