Factory that creates instances of PeriodFormatter.
Period formatting is performed by the
PeriodFormatter class.
Three classes provide factory methods to create formatters, and this is one.
The others are
ISOPeriodFormat and
PeriodFormatterBuilder .
PeriodFormat is thread-safe and immutable, and the formatters it returns
are as well.
