/**
 *  The `Interval2D` class represents a closed two-dimensional interval,
 *  which represents all points (x, y) with both `xmin <= x <= xmax` and
 *  `ymin <= y <= ymax`.
 *  Two-dimensional intervals are immutable: their values cannot be changed
 *  after they are created.
 *  The class `Interval2D` includes methods for checking whether
 *  a two-dimensional interval contains a point and determining whether
 *  two two-dimensional intervals intersect.
 *  <p>
 *  For additional documentation,
