Identify the context of the reference

[npch]

Ideally, we'd like to know what the context of the reference to a piece of software in a paper is, for example:

• it's software created by the author to do a key piece of work for the paper
• it's software created by the author that is described by the paper
• it's software used by the author to do the work in the paper

as we might hypothesise that the reusability of each type and likelihood that they're updated might be different.

This is required by some of the work proposed in #19.

Looking to see if we have a reference to the paper from the github repository would give us evidence that the paper falls into one of the first two categories and not the third. We could get that from the citation file (if it exists). See #18. However, if such a link does not exist it does not mean that the software does not fall into one of the first two categories.

That might work. Unfortunately, at present most repos won't have citation files of any sort. However a quick sample suggests that some repos do have a link to the paper in the readme - perhaps we could look for the DOI of the paper in the readme?
