This is a fairly large set of commits, but each discrete commit outlines removal of unused code, as well as the corresponding commit(s) that led up to it becoming unreachable.
I've attempted to make each commit both as discrete and thorough as makes sense (basically, I didn't want my removal to introduce further methods needing to be removed in other commits, creating a dependency).
Two commits include removal of Rubocop configuration - disabling long classes - that I included to keep the test suite green.
I've not been able to get lineman running locally, for whatever reason, so I'd only been running the test suite and Rubocop throughout this process.
I verified this in a browser, although there are others who might know where to be more thorough.
Please let me know if there's anything else I can do to help or explain these changes; I realize it's a fair bit to go through!
This removes the instance methods track_ids and archived_in from the profile presenter; these methods moved into an unreachable state in the commit 38ce25d.
This removes the following instance methods: * days * weeks * months These methods' usage were removed in acbd567.
Usage of this method was removed in cf59e78.
This removes the assignment presenter, corresponding test, and fixture file only used by the test. This presenter stopped being used in d3cf318.
Usage of repo_url was removed in 48962e2.
This removes the active_tracks helper, as well as the corresponding ExercismWeb::Presenters::Languages class (now unused), and corresponding test stubs that were also unnecessary. The most recent change removing usage of active_tracks was in ab545eb.
Both helper methods within ExercismWeb::Routes::Core were removed with a restructure of the views, where the markup was removed in c775850.
