Operations

A model of this concept must provide:

bool operator() (const Kernel::Point_3 &p, const 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.
