/**
 * A Duration object represents a period of time, like "2 months" or "1 day, 1 hour". Conceptually, it's just a map of units to their quantities, accompanied by some additional configuration and methods for creating, parsing, interrogating, transforming, and formatting them. They can be used on their own or in conjunction with other Luxon types; for example, you can use {@link DateTime.plus} to add a Duration object to a DateTime, producing another DateTime.
 *
 * Here is a brief overview of commonly used methods and getters in Duration:
 *
 * * **Creation** To create a Duration, use {@link Duration.fromMillis}, {@link Duration.fromObject}, or {@link Duration.fromISO}.
 * * **Unit values** See the {@link Duration.years}, {@link Duration.months}, {@link Duration.weeks}, {@link Duration.days}, {@link Duration.hours}, {@link Duration.minutes}, {@link Duration.seconds}, {@link Duration.milliseconds} accessors.
 * * **Configuration** See  {@link Duration.locale} and {@link Duration.numberingSystem} accessors.
 * * **Transformation** To create new Durations out of old ones use {@link Duration.plus}, {@link Duration.minus}, {@link Duration.normalize}, {@link Duration.set}, {@link Duration.reconfigure}, {@link Duration.shiftTo}, and {@link Duration.negate}.
 * * **Output** To convert the Duration into other representations, see {@link Duration.as}, {@link Duration.toISO}, {@link Duration.toFormat}, and {@link Duration.toJSON}
 *
 * There's are more methods documented below. In addition, for more information on subtler topics like internationalization and validity, see the external documentation.
