Class
    Foam::Vector
 
Description
    Templated 3D Vector derived from VectorSpace adding construction from
    3 components, element access using x(), y() and z() member functions and
    the inner-product (dot-product) and cross product operators.
 
    A centre() member function which returns the Vector for which it is called
    is defined so that point which is a typedef to Vector<scalar> behaves as
    other shapes in the shape hierarchy.
