/**
 *  The `Interval1D` class represents a one-dimensional interval.
 *  The interval is <em>closed</em>—it contains both endpoints.
 *  Intervals are immutable: their values cannot be changed after they are created.
 *  The class `Interval1D` includes methods for checking whether
 *  an interval contains a point and determining whether two intervals intersect.
 *  <p>
 *  For additional documentation,
