/// Age is a specialization of the FHIR Quantity datatype used to express a
/// duration of time during which an organism (or a process) has existed. It
/// carries a numerical value together with a coded unit of measure, and
/// optionally a comparator to indicate how the value should be understood.
///
/// In FHIR R5, an Age typically uses UCUM units of time (such as years, months,
/// or days) and constrains the underlying Quantity so that the value is not
/// negative. It is commonly used in clinical contexts such as age at onset,
/// age at diagnosis, or gestational age.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::age::Age;
///
/// let value = Age::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Age = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
