Apple model and functions to work with apples.
Notice how "core" in the doc string doesn't get linked ↑ - but core in this md does.
Extending "not converting parameter names to links" to markdown following a show_doc call
Pros
If we talk about core in the md following the Apple class, I think it's more likely that we're talking about the core parameter than the core module.
It's pretty confusing to hit a link that you think is talking about a param and be taken to docs for a different module - and it's quite common to mention params in md (e.g. nbdev_test_nbs mentions the fname param).
Cons
If you did want to link to the core module, you'd have to use a markdown link.
