Location of final code products

Currently, Snakefiles and other Snakemake code are in the compressed files in the files directory. Furthermore, they are inside a hidden .solutions directory inside those files. Would it be good to have them "more accessible", e.g. to move them to the code directory?

Another Snakemake lesson adds a reference Snakefile to the end of each episode which seems like a good idea to me.

That seems ok. A callout seems reasonable. One could also have it at the beginning of each episode, since not all items added in the previous episode are reused.
