Requires non CLI to trace through the appointments

[nus-se-script]

As mentioned in the textbook, the application should be constrained to typing (CLI) as the interaction method. This is a violation of the constraint, but since it does not mean that the entire feature cannot be used, it is considered as low severity.

Team's Response

Double clicking an appointment to trace it is functionally the same as typing “trace [appointment_id]”. As stated on the course website, we are NOT constrained to purely CLI inputs, but rather we are “CLI-first”. We implemented contact tracing through the CLI, and this double-clicking is an additional quality-of-life feature for users.

You can refer to our user guide section on "contact tracing" here.
