 * When called upon to parse a user command, the `AddressBookParser` class creates an `XYZCommandParser` (`XYZ` is a placeholder for the specific command name e.g., `AddPatientCommandParser`) which uses the other classes shown above to parse the user command and create a `XYZCommand` object (e.g., `AddPatientCommand`) which the `AddressBookParser` returns back as a `Command` object.
 * All `XYZCommandParser` classes (e.g., `AddPatientCommandParser`, `DeletePatientCommandParser`, ...) inherit from the `Parser` interface so that they can be treated similarly where possible e.g, during testing.
