## Kernel::LessXYZ_3

A model for this must provide:

bool

fo.operator() ( | Kernel::Point_3 p, Kernel::Point_3 q)

|  | returns true iff the x-coordinate of p is smaller than the x-coordinate of q or if the are the same and the y-coordinate of p is smaller than the y-coordinate of q, or, if both x- and y- coordinate are identical and the z-coordinate of p is smaller than the z-coordinate of q.
