 * 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.

/**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *

     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:

/**
 * 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 local}, {@link utc}, and (most flexibly) {@link fromObject}. To create one from a standard string format, use {@link fromISO}, {@link fromHTTP}, and {@link fromRFC2822}. To create one from a custom string format, use {@link fromFormat}. To create one from a native JS date, use {@link fromJSDate}.
 * * **Gregorian calendar and time**: To examine the Gregorian properties of a DateTime individually (i.e as opposed to collectively through {@link toObject}), use the {@link year}, {@link month},
 * {@link day}, {@link hour}, {@link minute}, {@link second}, {@link millisecond} accessors.
 * * **Week calendar**: For ISO week calendar attributes, see the {@link weekYear}, {@link weekNumber}, and {@link weekday} accessors.
 * * **Configuration** See the {@link locale} and {@link numberingSystem} accessors.
 * * **Transformation**: To transform the DateTime into other DateTimes, use {@link set}, {@link reconfigure}, {@link setZone}, {@link setLocale}, {@link plus}, {@link minus}, {@link endOf}, {@link startOf}, {@link toUTC}, and {@link toLocal}.
 * * **Output**: To convert the DateTime to other representations, use the {@link toRelative}, {@link toRelativeCalendar}, {@link toJSON}, {@link toISO}, {@link toHTTP}, {@link toObject}, {@link toRFC2822}, {@link toString}, {@link toLocaleString}, {@link toFormat}, {@link toMillis} and {@link 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.

/**
 * 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}
