The Geometry package contains classes for representing geometric entities like points and lines, and some algebraic/geometric primitives for operating on them, like norms, distances, and intersections.
Please note that things in this package have been developed in an ad-hoc fashion, driven by the needs of the various GrAL algorithms, and do not represent an attempt to provide a `complete' set of primitives (whatever this would mean).
I tried to make geometric and algebraic algorithms as generic as possible. The main technique for achieving this aim is a traits technique giving uniform access to the functionality of geometric point classes via specializations of the point_traits template.
