/**
* Factory that creates instances of DateTimeFormatter based on the ISO8601 standard.
*
* Date-time formatting is performed by the {@link DateTimeFormatter} class.
* Three classes provide factory methods to create formatters, and this is one.
* The others are {@link DateTimeFormat} and {@link DateTimeFormatterBuilder}.
*
* ISO8601 is the international standard for data interchange. It defines a
* framework, rather than an absolute standard. As a result this provider has a
* number of methods that represent common uses of the framework. The most common
* formats are {@link #date() date}, {@link #time() time}, and {@link #dateTime() dateTime}.
*
* For example, to format a date time in ISO format:
*
* DateTime dt = new DateTime();
* DateTimeFormatter fmt = ISODateTimeFormat.dateTime();
* String str = fmt.print(dt);
*
*
* Note that these formatters mostly follow the ISO8601 standard for printing.
* For parsing, the formatters are more lenient and allow formats that are not
* in strict compliance with the standard.
*
* It is important to understand that these formatters are not linked to
* the ISOChronology. These formatters may be used with any
* chronology, however there may be certain side effects with more unusual
* chronologies. For example, the ISO formatters rely on dayOfWeek being
* single digit, dayOfMonth being two digit and dayOfYear being three digit.
* A chronology with a ten day week would thus cause issues. However, in
* general, it is safe to use these formatters with other chronologies.
*
* ISODateTimeFormat is thread-safe and immutable, and the formatters it
* returns are as well.

/**
* Returns a formatter that outputs only those fields specified.
*
* This method examines the fields provided and returns an ISO-style
* formatter that best fits. This can be useful for outputting
* less-common ISO styles, such as YearMonth (YYYY-MM) or MonthDay (--MM-DD).
*
* The list provided may have overlapping fields, such as dayOfWeek and
* dayOfMonth. In this case, the style is chosen based on the following
* list, thus in the example, the calendar style is chosen as dayOfMonth
* is higher in priority than dayOfWeek:
*
* - monthOfYear - calendar date style
*
- dayOfYear - ordinal date style
*
- weekOfWeekYear - week date style
*
- dayOfMonth - calendar date style
*
- dayOfWeek - week date style
*
- year
*
- weekyear
*
* The supported formats are:
*

* 2005-03-25 20050325 year/monthOfYear/dayOfMonth
* 2005-03 2005-03 year/monthOfYear

* If the input collection is unmodifiable then no side effect occurs.
