Adds, verbatim the first three episodes of Unix Shell

[ns-rse]

Copies over verbatim the first three chapters of the Unix Shell software carpentry.

This not the final format. Revisions will be made to trim down, but before hacking at the material I wanted to get everything copied over and in subsequent revisions decide what material to keep.

In copying these files over I have made sure the material renders correctly (initially I missed out all the figures!).

Currently the example data is not included as I figured we would customise this to the sample data that we set up the course to use which currently is undecided (see #12).

What does this mean?

If you have source files that require output and figures to be generated (e.g. R Markdown), then it is important to make sure the generated figures and output are reproducible.

This output provides a way for you to inspect the output in a diff-friendly manner so that it's easy to see the changes that occur due to new software versions or randomisation.

Happy for this to be merged, both text and images render correctly when tested in R and I agree that this forms a good basis for our own introduction section. 👍
