 * \brief     This is the entry point of the program; it contains the \b "main" function
 *
 * \details   This is the principal file of the project; it executes the three threads necessary
 *            for the program execution ( the threads tcpdump_function, pcap_function, et ClearOutdatedValues ).
 *            The microHttpServer is also inialised and called in this file.
