-/*
- * This file handles parsing for well-specified formats. Here's how it works:
- * Two things go into parsing: a regex to match with and an extractor to take apart the groups in the match.
- * An extractor is just a function that takes a regex match array and returns a { year: ..., month: ... } object
- * parse() does the work of executing the regex and applying the extractor. It takes multiple regex/extractor pairs to try in sequence.
- * Extractors can take a "cursor" representing the offset in the match to look at. This makes it easy to combine extractors.
- * combineExtractors() does the work of combining them, keeping track of the cursor through multiple extractions.
- * Some extractions are super dumb and simpleParse and fromStrings help DRY them.

-/**
- * 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.

- * An Interval object represents a half-open interval of time, where each endpoint is a {@link DateTime}. Conceptually, it's a container for those two endpoints, accompanied by methods for creating, parsing, interrogating, comparing, transforming, and formatting them.
- *
- * Here is a brief overview of the most commonly used methods and getters in Interval:
- *
- * * **Creation** To create an Interval, use {@link Interval#fromDateTimes}, {@link Interval#after}, {@link Interval#before}, or {@link Interval#fromISO}.
- * * **Accessors** Use {@link Interval#start} and {@link Interval#end} to get the start and end.
- * * **Interrogation** To analyze the Interval, use {@link Interval#count}, {@link Interval#length}, {@link Interval#hasSame}, {@link Interval#contains}, {@link Interval#isAfter}, or {@link Interval#isBefore}.
- * * **Transformation** To create other Intervals out of this one, use {@link Interval#set}, {@link Interval#splitAt}, {@link Interval#splitBy}, {@link Interval#divideEqually}, {@link Interval#merge}, {@link Interval#xor}, {@link Interval#union}, {@link Interval#intersection}, or {@link Interval#difference}.
- * * **Comparison** To compare this Interval to another one, use {@link Interval#equals}, {@link Interval#overlaps}, {@link Interval#abutsStart}, {@link Interval#abutsEnd}, {@link Interval#engulfs}
- * * **Output** To convert the Interval into other representations, see {@link Interval#toString}, {@link Interval#toISO}, {@link Interval#toISODate}, {@link Interval#toISOTime}, {@link Interval#toFormat}, and {@link Interval#toDuration}.

-/**
- * A DateTime is an immutable data structure representing a specific date and time and accompanying methods. It contains class and instance methods for creating, parsing, interrogating, transforming, and formatting them.
- *
- * A DateTime comprises of:
- * * A timestamp. Each DateTime instance refers to a specific millisecond of the Unix epoch.
- * * A time zone. Each instance is considered in the context of a specific zone (by default the local system's zone).
- * * Configuration properties that effect how output strings are formatted, such as `locale`, `numberingSystem`, and `outputCalendar`.
- *
- * Here is a brief overview of the most commonly used functionality it provides:
- *
- * * **Creation**: To create a DateTime from its components, use one of its factory class methods: {@link DateTime#local}, {@link DateTime#utc}, and (most flexibly) {@link DateTime#fromObject}. To create one from a standard string format, use {@link DateTime#fromISO}, {@link DateTime#fromHTTP}, and {@link DateTime#fromRFC2822}. To create one from a custom string format, use {@link DateTime#fromFormat}. To create one from a native JS date, use {@link DateTime#fromJSDate}.
- * * **Gregorian calendar and time**: To examine the Gregorian properties of a DateTime individually (i.e as opposed to collectively through {@link DateTime#toObject}), use the {@link DateTime#year}, {@link DateTime#month},
- * {@link DateTime#day}, {@link DateTime#hour}, {@link DateTime#minute}, {@link DateTime#second}, {@link DateTime#millisecond} accessors.
- * * **Week calendar**: For ISO week calendar attributes, see the {@link DateTime#weekYear}, {@link DateTime#weekNumber}, and {@link DateTime#weekday} accessors.
- * * **Configuration** See the {@link DateTime#locale} and {@link DateTime#numberingSystem} accessors.
- * * **Transformation**: To transform the DateTime into other DateTimes, use {@link DateTime#set}, {@link DateTime#reconfigure}, {@link DateTime#setZone}, {@link DateTime#setLocale}, {@link DateTime.plus}, {@link DateTime#minus}, {@link DateTime#endOf}, {@link DateTime#startOf}, {@link DateTime#toUTC}, and {@link DateTime#toLocal}.
- * * **Output**: To convert the DateTime to other representations, use the {@link DateTime#toRelative}, {@link DateTime#toRelativeCalendar}, {@link DateTime#toJSON}, {@link DateTime#toISO}, {@link DateTime#toHTTP}, {@link DateTime#toObject}, {@link DateTime#toRFC2822}, {@link DateTime#toString}, {@link DateTime#toLocaleString}, {@link DateTime#toFormat}, {@link DateTime#toMillis} and {@link DateTime#toJSDate}.
- *
- * There's plenty others documented below. In addition, for more information on subtler topics like internationalization, time zones, alternative calendars, validity, and so on, see the external documentation.
