///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  SRFSTR     I   Surface name or ID string.
///  BODYID     I   Body ID code.
///  CODE       O   Integer surface ID code.
///  FOUND      O   Flag indicating whether surface ID was found.
/// ```
///
/// # Detailed Input
///
/// ```text
///  SRFSTR   is a string designating a surface. SRFSTR may contain
///           a surface name or a string representation of the
///           surface's integer ID code.
///
///           If, for the body specified by BODYID, multiple surface
///           names are associated with one surface ID code, then any
///           of these names may be used as the value of SRFSTR.
///
///           Case and leading and trailing blanks in a surface name
///           are not significant. Sequences of consecutive embedded
///           blanks are considered equivalent to a single blank.
///           For example, all of the strings below are considered
///           to be equivalent:
///
///              'MGS MOLA 128 PIXEL/DEG'
///              'MGS MOLA 128 pixel/deg'
///              'MGS MOLA 128 PIXEL/DEG   '
///              'MGS MOLA 128    PIXEL/DEG'
///              '   MGS MOLA 128 PIXEL/DEG'
///
///           However,
///
///              'MGSMOLA 128PIXEL/DEG'
///
///           is not equivalent to the names above.
///
///
///  BODYID   is the integer ID code of the body associated with the
///           surface designated by SRFSTR.
/// ```
///
/// # Detailed Output
///
/// ```text
///  CODE     is integer ID code of the surface designated by
///           SRFSTR, for the body designated by BODYID, if for this
///           body an association exists between the input surface
///           string and a surface ID code. CODE is defined if and
///           only if the output flag FOUND is .TRUE.
///
///  FOUND    is a logical flag that is .TRUE. if a surface code
///           corresponding to the input surface string and body ID
///           code was found. FOUND is .FALSE. otherwise.
/// ```
///
/// # Exceptions
///
/// ```text
///  1)  If the input surface string does not map to an ID code
///      and does not represent an integer, the output CODE is
///      undefined and the output FOUND is set to .FALSE.
///
///      This case is not treated as an error.
/// ```
///
/// # Files
///
/// ```text
///  Surface name-to-ID mappings may be defined at run time by loading
///  text kernels containing kernel variable assignments of the form
///
///     NAIF_SURFACE_NAME += ( <surface name 1>, ... )
///     NAIF_SURFACE_CODE += ( <surface code 1>, ... )
///     NAIF_SURFACE_BODY += ( <body code 1>,    ... )
///
///  Above, the Ith elements of the lists on the assignments' right
///  hand sides together define the Ith surface name/ID mapping.
///
///  The same effect can be achieved using assignments formatted as
///  follows:
///
///     NAIF_SURFACE_NAME += <surface name 1>
///     NAIF_SURFACE_CODE += <surface code 1>
///     NAIF_SURFACE_BODY += <body code 1>
///
///     NAIF_SURFACE_NAME += <surface name 2>
///     NAIF_SURFACE_CODE += <surface code 2>
///     NAIF_SURFACE_BODY += <body code 2>
///
///        ...
///
///  Note the use of the
///
///     +=
///
///  operator; this operator appends to rather than overwrites the
///  kernel variable named on the left hand side of the assignment.
/// ```
///
/// # Particulars
///
/// ```text
///  Surfaces are always associated with bodies (which usually are
///  ephemeris objects). For any given body, a mapping between surface
///  names and surface ID codes can be established.
///
///  Bodies serve to disambiguate surface names and ID codes: the set
///  of surface names and surface ID codes for a given body can be
///  thought of as belonging to a name space. A given surface ID code
///  or surface name may be used for surfaces of multiple bodies,
///  without conflict.
///
///  Associations between surface names and ID codes are always made
///  via kernel pool assignments; there are no built-in associations.
///
///  SRFSCC is one of four related subroutines:
///
///     SRFS2C      Surface string and body string to surface ID code
///     SRFSCC      Surface string and body ID code to surface ID code
///     SRFC2S      Surface ID code and body ID code to surface string
///     SRFCSS      Surface ID code and body string to surface string
///
///  SRFS2C, SRFC2S, SRFSCC, and SRFCSS perform translations between
///  surface strings and their corresponding integer ID codes.
///
///  Refer to naif_ids.req for details concerning adding new surface
///  name/code associations at run time by loading text kernels.
/// ```
///
/// # Examples
///
/// ```text
///  The formatting of the results shown for this example may differ
///  across platforms.
///
///  1) Supposed a text kernel has been loaded that contains
///     the following assignments:
///
///        NAIF_SURFACE_NAME += ( 'MGS MOLA  64 pixel/deg',
///                               'MGS MOLA 128 pixel/deg',
///                               'PHOBOS GASKELL Q512'     )
///        NAIF_SURFACE_CODE += (   1,   2,    1 )
///        NAIF_SURFACE_BODY += ( 499, 499,  401 )
///
///     Translate each surface string and body ID pair to the
///     associated surface ID code. Also perform a translation
///     for a surface name having no matching ID.
