/**
 * <p>The Explorer piece by Leander Herzog demonstrates the use of polar
 * coordinates for steering and Line2D instances for finding line intersections.
 * The underlying process of the piece is as follows: update steering
 * direction, move forward if no existing line is being crossed, else search
 * for a new direction.</p>
 *
 * <p>Ported to toxiclibs & extended by Karsten Schmidt. The process is now
 * also utilizing a flexible BoundaryCheck interface to define its outer shape.
 * The demo includes a rectangular & circular boundary implementation, but
 * you're encouraged to try out more complex shapes as an exercise.</p>
