  15 C arrays are adapted to the Boost.Geometry point concept

  17 [heading Description]
  18
  19 C arrays, such as double[2] or int[3], are (optionally) adapted to the Boost.Geometry
  20 point concept. They can therefore be used in many Boost.Geometry algorithms.
  21
  22 Note that a C array cannot be the point type of a linestring or a polygon. The reason
  23 for that is that a std::vector does not allow containing C arrays
  24 (this is not related to Boost.Geometry). The C array is therefore limited to
  25 the point type.
