This PR contains all the work related to setting up this project as required to implement the [Assignment](https://repo.rock-n-code.com/rock-n-code/deep-linking-assignment/wiki/Assignment) on top, as intended. To summarise this work: - [x] created a new **Xcode** project; - [x] cloned the `Wikipedia` app and inserted it into the **Xcode** project; - [x] created the `Locations` app and also, its `Libraries` package; - [x] created the `Shared` package to share dependencies between the apps; - [x] added a `Makefile` file and implemented some **environment** and **help** commands.

/// DEPRECATED: This should only be used for migrating legacy data to the new cache format. The app should no longer need to store information in extended file attributes. Previously, this was used to store the MIME type of a cached file so the approrpriate Content-Type could be set when serving it as a cached response. Now, the response headers are cached in a separate file, removing the need to attach MIME type (or any other info) to the file itself. This function can be removed when the corresponding migration is removed.
