    \brief The SoMFVec4d class is a container for SbVec4d vectors.
  
    \ingroup fields
  
    This field is used where nodes, engines or other field containers
    need to store an array of vectors with four elements.
  
    This field supports application data sharing through a
    setValuesPointer() method. See SoMField documentation for
    information on how to use this function.
