This is a very quick demo of using the {targests} package.
In this, I have run the function use_targets() to generate the initial targets script, then edited it to use the
code that I have created for this demo.
You can run the pipeline using tar_make().
Note that these are all dummy scripts that don't do anything particularly useful. In practice, you would want to create a quarto document and actually render it, in this I just return a filename.
