  // ------------------TO BE IMPLEMENTED---------------------
  // Testing the intersection of individual phi faces is
  // pretty straight forward. The simple thing therefore is to
  // form a loop and check them all in sequence.
  //
  // But, I worry about one day someone making
  // a polygon with a thousands sides. A linear search
  // would not be ideal in such a case.
  //
  // So, it would be nice to be able to quickly decide
  // which face would be intersected. One can make a very
  // good guess by using the intersection with a cone.
  // However, this is only reliable in 99% of the cases.
  //
  // My solution: make a decent guess as to the one or
  // two potential faces might get intersected, and then
  // test them. If we have the wrong face, use the test
  // to make a better guess.
  //
  // Since we might have two guesses, form a queue of
  // potential intersecting faces. Keep an array of 
  // already tested faces to avoid doing one more than
  // once.
