// Computes necessary generic information for boolean operations by

// Inputs:
// V #V by 3 list of vertex positions
// F #F by 3 list of triangle indices into V
// Outputs:
// I #F list of which peel Iation a facet belongs
// flip #F list of whether a facet's orientation was flipped when facet
// "peeled" into its associated outer hull layer.
// Returns number of peels
