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.
