// Class mapping manager functionality.                                 //
// On masters it keeps info about the available worker nodes and allows //
// communication with them. In particular, it reads the proof.conf file //
// when working with static resources.                                  //
// On workers it handles the communication with the master              //
// (to be implemented).                                                 //
