Generation of appoggiatura and accacciatura

In many scores, Pierre Boulez use a lot of accacciatura or appoggiatura , for exemple like in Dérive (1984), a score composed for and based on the name SACHER (famous hexachord used also in "Message esquisse").

Here's a function to help to add such appoggiature in your score based on a list of rhythmic values.

There is a draft doc in French joined to the function definition.

Hope it could be useful for some of us and may be improved and better coded and refined.

My best to all of Opmo users.
