Linting and autmated checking

[alisterde]

Implementing automating linting check to workflow (this pull requested will check if I have set this up correctly), and adding linting instructions to README. As issue #28

This will be very helpful, thanks @alisterde

Thanks @alisterde -- once you've addressed @rcw5890 's concerns, I'm happy for this to go in.

The new readme comments look great, but there's now an unnecessary table appearing at the top of the readme here
@ben18785 I think you figured out how to prevent this?

[alisterde]

Thanks @rcw5890! I think the readme my table might be from knitr::knit("README.Rmd"), I've tried something. I've also noticed there was a formatting error with the bullet points of the style guide, though it was fine when I was previewing it. Also thanks for looking at the automated Ubuntu release lint testing, it's quite frustrating!

Hi @rcw5890 the table is now gone from the top of the readme, and the bullet points are correctly formatted.

Thanks @alisterde this looks ready to go.

It definitely is. I suspect there is some way to fix it, but I am in favor of merging this now so any imminent code contributions get checked properly.
