Ok thank you. This is just experimental code actually, in order to 
change color of bodies which have at least one broken interaction. But 
let you correct this if you feel like doing it (based on classIndex 
probably?).

One technical question : when one write "if (c1 && c2 && c3)", are tests 
c2 and c3 still evaluated when c1 is  "false"?
