// The following is an example trickle handler.
// It echoes whatever the app sent us, as a trickle-down message.
// Replace it with your own function.

// Note: you're passed the host ID (in mfh.hostid).
// From this you can get the HOST and USER records with
// DB_HOST host;
// DB_USER user;
// host.lookup_id(mfh.hostid);
// user.lookup_id(host.userid);
