IPC Project - Multi-threading programming (continued)

In a second step, a new requirement from the customer has been received: besides the reports of the Operators and Subscribers as already designed, a report type for Security means has been required: by typing a subscriber id, the system would permit the user to get a report of all its “first circle” contacts and its “second circle” contacts (i.e. “first circle” contacts of this specific subscribers' “first circle” contacts).
