public class PlaneParallelLineGenerator extends Object implements ParallelLineGenerator
All the lines pass through a point on a d * d plane, where d = the longest diagonal of a 3D interval. The lines are also normal to the plane.
The plane is d * d so that it's big enough that normal lines passing through it cover the entire interval, regardless of the orientation of the plane. However, this means that nextLine() might return a line that entirely misses the interval.

If the class is initialised with more than one section, then lines pass the plane cyclically through each section. For example, if sections == 2 then the next four lines come from the four different quadrants of the plane. Calling nextLine() for the fifth time resets the cycle. Each line has the same random offset within its section. This offset is randomized when the cycle resets. The order of the quadrants is randomised as well.
NB: the line might miss the interval the class was initialised with!
