/**
* @name setDefaultOptions
* @category Common Helpers
* @summary Set default options including locale.
* @pure false
*
* @description
* Sets the defaults for
* `options.locale`, `options.weekStartsOn` and `options.firstWeekContainsDate`
* arguments for all functions.
*
* @param {Object} newOptions - an object with options.
* @param {Locale} [newOptions.locale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
* @param {0|1|2|3|4|5|6} [newOptions.weekStartsOn] - the index of the first day of the week (0 - Sunday)
* @param {1|2|3|4|5|6|7} [newOptions.firstWeekContainsDate] - the day of January, which is always in the first week of the year
* @throws {TypeError} 1 argument required
*
* @example
* // Set global locale:
* import { es } from 'date-fns/locale'
* setDefaultOptions({ locale: es })
* const result = format(new Date(2014, 8, 2), 'PPPP')
* //=> 'martes, 2 de septiembre de 2014'
*
* @example
* // Start of the week for 2 September 2014:
* const result = startOfWeek(new Date(2014, 8, 2))
* //=> Sun Aug 31 2014 00:00:00
*
* @example
* // Start of the week for 2 September 2014,
* // when we set that week starts on Monday by default:
* setDefaultOptions({ weekStartsOn: 1 })
* const result = startOfWeek(new Date(2014, 8, 2))
* //=> Mon Sep 01 2014 00:00:00
*
* @example
* // Manually set options take priority over default options:
* setDefaultOptions({ weekStartsOn: 1 })
* const result = startOfWeek(new Date(2014, 8, 2), { weekStartsOn: 0 })
* //=> Sun Aug 31 2014 00:00:00
*
* @example
* // Remove the option by setting it to `undefined`:
* setDefaultOptions({ weekStartsOn: 1 })
* setDefaultOptions({ weekStartsOn: undefined })
* const result = startOfWeek(new Date(2014, 8, 2))
* //=> Sun Aug 31 2014 00:00:00
