Compares this date to another date, including the chronology.
!(p)
The comparison is based first on the underlying time-line date, then
on the chronology.
It is "consistent with equals", as defined by {@link Comparable}.
!(p)
For example, the following is the comparator order:
!(ol)
!(li){@code 2012-12-03 (ISO)}</li>
!(li){@code 2012-12-04 (ISO)}</li>
!(li){@code 2555-12-04 (ThaiBuddhist)}</li>
!(li){@code 2012-12-05 (ISO)}</li>
</ol>
Values #2 and #3 represent the same date on the time-line.
When two values represent the same date, the chronology ID is compared to distinguish them.
This step is needed to make the ordering "consistent with equals".
!(p)
If all the date objects being compared are _in the same chronology, then the
additional chronology stage is not required and only the local date is used.
To compare the dates of two {@code TemporalAccessor} instances, including dates
_in two different chronologies, use {@link ChronoField#EPOCH_DAY} as a comparator.
!(p)
This implementation performs the comparison defined above.
@param other the other date to compare to, not null
@return the comparator value, negative if less, positive if greater
