/// Determine whether a point is an element of a double precision

/// # Required Reading
///
/// * [WINDOWS](crate::required_reading::windows)
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// POINT I Input point.
/// WINDOW I Input window.
///
/// The function returns .TRUE. if POINT is an element of WINDOW.
/// ```
///
/// # Detailed Input
///
/// ```text
/// POINT is a point, which may or may not be contained in one of
/// the intervals in WINDOW.
///
/// WINDOW is a SPICE window containing zero or more intervals.
/// ```
///
/// # Detailed Output
///
/// ```text
/// The function returns .TRUE. if the input point is an element of
/// the input window --- that is, if
///
/// a(i) < POINT < b(i)
/// - -
///
/// for some interval [ a(i), b(i) ] in WINDOW --- and returns .FALSE.
/// otherwise.
/// ```
///
/// # Exceptions
///
/// ```text
/// 1) The cardinality of the input WINDOW must be even. Left
/// endpoints of stored intervals must be strictly greater than
/// preceding right endpoints. Right endpoints must be greater
/// than or equal to corresponding left endpoints. Invalid window
/// data are not diagnosed by this routine and may lead to
/// unpredictable results.
/// ```
///
/// # Examples
///
/// ```text
/// Let A contain the intervals
///
/// [ 1, 3 ] [ 7, 11 ] [ 23, 27 ]
///
/// Then the following expressions are true
///
/// WNELMD ( 1, WINDOW )
/// WNELMD ( 9, WINDOW )
///
/// and the following expressions are false.
///
/// WNELMD ( 0, WINDOW )
/// WNELMD ( 13, WINDOW )
/// WNELMD ( 29, WINDOW )
