ISODateTimeFormat

```
public class ISODateTimeFormat
extends java.lang.Object
```
Factory that creates instances of DateTimeFormatter based on the ISO8601 standard.
Date-time formatting is performed by the DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are DateTimeFormat and 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 date, time, and 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.

public static DateTimeFormatter forFields(java.util.Collection<DateTimeFieldType> fields,
                                          boolean extended,
                                          boolean strictISO)
```
    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:

    * indicates that this is not an official ISO format and can be excluded by passing in strictISO as true.
    This method can side effect the input collection of fields. If the input collection is modifiable, then each field that was added to the formatter will be removed from the collection, including any duplicates. If the input collection is unmodifiable then no side effect occurs.
    This side effect processing is useful if you need to know whether all the fields were converted into the formatter or not. To achieve this, pass in a modifiable list, and check that it is empty on exit.
    Parameters:
    
    fields - the fields to get a formatter for, not null, updated by the method call unless unmodifiable, removing those fields built in the formatter
    
    extended - true to use the extended format (with separators)
    
    strictISO - true to stick exactly to ISO8601, false to include additional formats
    
    Returns:
    
    a suitable formatter
    
    Throws:
    
    java.lang.IllegalArgumentException - if there is no format for the fields
