Added some additional explanation of the header word that describes the number of analog samples in a 3D frame.
Updated the definition of the FORCE_PLATFORM:ZERO parameter to make it clear that only a value of 0,0 indicates that no baseline offset correction is to be applied to the force platform data.
Minor grammatical changes to reserve the word “section” for use with parts of the C3D file description and avoid confusion with parts of the manual and documentation.
