Ajout des premiers bouts de code pour les tests :
test1 = prise de son via pulse audio (à l'arache avec le modèle "simple") test2 = premières illuminations avec le projo LED test3 = fade R/G/B et jeu avec les problématiques de timing test4 = à faire : Appli GTK pour assembler les tests précédents git-svn-id: file:///var/svn/2012-violon-leds/trunk@2 6be1fa4d-33ac-4c33-becc-79fcb3794bb6
