is_phintish

This function returns <code>TRUE</code> for <code>&lt;phinterval&gt;</code> and <code>&lt;Interval&gt;</code> vectors and
returns <code>FALSE</code> otherwise.

Implements the phinterval vector class for representing time
spans that may contain gaps (disjoint intervals) or be empty. This class
generalizes the 'lubridate' package's interval class to support vectorized
set operations (intersection, union, difference, complement) that always
return a valid time span, even when disjoint or empty intervals are created.
