Examples:
List all courselinks where I'm a receiver of:
participant.sh get /campusconnect/courselinks
or
participant.sh -r get /campusconnect/courselinks
List all courselinks where I'm the sender of:
participant.sh -s get /campusconnect/courselinks
Show the courselink representation with id 2257:
participant.sh get /campusconnect/courselinks/2257
Delete the courselink representation with id 2257:
participant.sh delete /campusconnect/courselinks/2257
Delete courselinks where I'm a receiver of:
participant.sh -r delete /campusconnect/courselinks
Delete courselinks where I'm the senedr of:
participant.sh -s delete /campusconnect/courselinks
Delete courselinks where I'm a receiver or sender of:
participant.sh -a delete /campusconnect/courselinks
