-The `address` field in `Person` is actually an instance of the `seedu.address.model.contact.Address` class. Since removing the `Address` class will break the application, we start by identifying `Address`'s usages. This allows us to see code that depends on `Address` to function properly and edit them on a case-by-case basis. Right-click the `Address` class and select `Refactor` \> `Safe Delete` through the menu.
