Get the start, end or duration of a datey_interval

Get the start, end or duration of a datey_interval using the syntax $start, $end or $duration respectively.

$duration is the duration of the interval provided it is proper (i.e. start <= end). If the interval is improper then $durationis NA_durationy_. When x is a datey_interval then x$duration is identical to durationy(x).
