struct PK_section_r_s
    {
    PK_BODY_array_t front_bodies;  --- Bodies in front of section
    PK_BODY_array_t back_bodies;   --- Bodies behind section

This structure contains the results of a section operation for bodies
or faces.

Used in:

PK_BODY_section_with_sheet
PK_BODY_section_with_surf
PK_FACE_section_with_sheet
PK_section_r_f

The arrays of entities are returned under the control of the 'fence'
field of an options structure, and will be set to (NULL, 0) if not
requested, or empty (length of zero).

The function PK_section_r_f may be used to free associated memory.
