// This class provides a widget to represent an edit a matrix of permissions
// for services and friends. The widget allows to:
// - set permission for each friend/service combination
// - set permissions for a given service all friends at once
// - set permissions for a given friend, all services at once
//
// The code can also be used to display bandwidth for each (friend,service) combination.
// Maybe we should in the future make a base class with the matrix structure and use it for
// various display usages.
