//actorList is a vector which holds pointers of actor classes
//in an actor class there is an integer (dist) which represents the distance of
// current actor to another one. this function is supposed to generate new
// distances in map and if distance already exists in the map, dist map
// increases the value part of key. for instance, all actors whose distance 
//is 5 count on map dist[5][n], n shows the total number of actors. if there
// is no key=5 in the map, it simply creates one and adds it to the map (using make_pair(_,_)).
