/// Find the first occurrence in a string of a character NOT belonging

/// searching forwards.
///
/// # Required Reading
///
/// * [SCANNING](crate::required_reading::scanning)
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// STR I Any character string.
/// CHARS I A collection of characters.
/// START I Position to begin looking for one not in CHARS
///
/// The function returns the index of the first character of STR
/// at or following index START that is not in the collection CHARS.
/// ```
///
/// # Detailed Input
///
/// ```text
/// STR is any character string.
///
/// CHARS is a character string containing a collection of
/// characters. Spaces in CHARS are significant.
///
/// START is the position in STR to begin looking for
/// characters not in CHARS.
/// ```
///
/// # Detailed Output
///
/// ```text
/// The function returns the index of the first character of STR (at
/// or following index START) that is not one of the characters in the
/// string CHARS. If no such character is found, the function returns
/// zero.
/// ```
///
/// # Exceptions
///
/// ```text
/// Error free.
///
/// 1) If START is less than 1, the search begins at the first
/// character of the string.
///
/// 2) If START is greater than the length of the string, NCPOS
/// returns zero.
/// ```
///
/// # Particulars
///
/// ```text
/// NCPOS is case sensitive.
///
/// An entire family of related SPICELIB routines (POS, CPOS, NCPOS,
/// POSR, CPOSR, NCPOSR) is described in the Required Reading.
///
/// Those familiar with the True BASIC language should note that
/// these functions are equivalent to the True BASIC intrinsic
/// functions with the same names.
/// ```
///
/// # Examples
///
/// ```text
/// Let STRING = 'BOB, JOHN, TED, AND MARTIN '
/// 123456789012345678901234567890
///
/// Let CHAR = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
///
/// Normal (Sequential) Searching:
/// ------------------------------
///
/// NCPOS( STRING, CHAR, 1 ) = 4
/// NCPOS( STRING, CHAR, 5 ) = 5
/// NCPOS( STRING, CHAR, 6 ) = 10
/// NCPOS( STRING, CHAR, 11 ) = 11
/// NCPOS( STRING, CHAR, 12 ) = 15
/// NCPOS( STRING, CHAR, 16 ) = 16
/// NCPOS( STRING, CHAR, 17 ) = 20
/// NCPOS( STRING, CHAR, 21 ) = 27
/// NCPOS( STRING, CHAR, 28 ) = 28
/// NCPOS( STRING, CHAR, 29 ) = 29
/// NCPOS( STRING, CHAR, 30 ) = 30
/// NCPOS( STRING, CHAR, 31 ) = 0
///
/// START out of bounds:
/// --------------------
///
/// NCPOS( STRING, CHAR, -12 ) = 4
/// NCPOS( STRING, CHAR, 0 ) = 4
/// NCPOS( STRING, CHAR, 31 ) = 0
/// NCPOS( STRING, CHAR, 123 ) = 0
///
/// Order within CHARS:
/// -------------------
///
/// NCPOS( STRING, 'JOHN', 7 ) = 10
/// NCPOS( STRING, 'OHJN', 7 ) = 10
