Points in Boost.Geometry

Boost.Geometry states a set of requirements that a point must meet (a point interface or point concept) in order to work with the other components.

Points are constructed, then manipulated:

1. Points are constructed, usually with parameters {x₀, ... x_{n - 1}}.

2. A point's coordinates is accessed through either:

   1. Namespace scoped functions:

      boost::geometry::get<INDEX>(const POINT&)
          boost::geometry::set<INDEX>(POINT&, VALUE)

   2. or templatized member functions:

      boost::geometry::point_type::get<INDEX>()
          boost::geometry::point_type::set<INDEX>(VALUE)
