/**
* Checks if this chronology is ISO based.
* <p>
* An ISO based chronology has the same basic structure as the {@link IsoChronology
* ISO chronology}, i.e., the chronology has the same number of months, the number
* of days in each month, and day-of-year and leap years are the same as ISO chronology.
* It also supports the concept of week-based-year of ISO chronology.
* For example, the {@link MinguoChronology Minguo}, {@link ThaiBuddhistChronology
* ThaiThaiBuddhist} and {@link JapaneseChronology Japanese} chronologies are ISO based.
*
* @implSpec
* The default implementation returns {@code false}.
*
* @return {@code true} only if all the fields of {@link IsoFields} are supported by
* this chronology. Otherwise, returns {@code false}.
