// update_stats:
// Update average credit for idle users, hosts and teams.
// These fields are updates as new credit is granted;
// the purpose of this program is to decay credit of entities
// that are inactive for long periods.
// Hence it should be run about once a day at most.
//
// Also updates the nusers field of teams
//
// usage: update_stats [-update_teams] [-update_users] [-update_hosts] [-asynch]
