+ *  when something is wrong.  This function compares the notes directly, without trying to hint when a note
+ *  has the right code but the wrong metadata.  It's useful for lists of notes coming from multi-CPL DCPs.
+ *  Normally check_verify_result() gives output which is easier to understand when something is wrong.
