Title: Add in a diagram showing redirects and pipes

Based on an initial discussion in swcarpentry/bc#817. I've modified the diagram quite a lot since then, but I think this version is clearer and more descriptive. It also fits in better with the discussion comparing redirects and pipes towards the end of the lesson rather than with the examples earlier on.
