ntvy sorting scheme

[maieul]

Maybe we could add the following sorting scheme

\DeclareSortingScheme{ntyv}{
\sort{
\field{presort}
}
\sort[final]{
\field{sortkey}
}
\sort{
\field{sortname}
\field{author}
\field{editor}
\field{translator}
\field{sorttitle}
\field{title}
}
\sort{
\field{sorttitle}
\field{title}
}
\sort{
\field{volume}
\literal{0}
}
\sort{
\field{sortyear}
\field{year}
}
}

Some time, the volume are not published in there order number, and as the volume field is printed before the year field…

Again, I'd rather not put things in the core which are discipline or style specific since it's easy to modify.
