The patch adds a vector lib I have put together during the last time,
it is just handy and interfaces well with s(s)g*. Together with some small
modifications this will later also interface well with OpenSceneGraphs
vectors/matrices. Using this vector kernel is targeted to have a handy
matrix/vector lib available and to provide a scenegraph independent vector
type for use with a small scenegraph wrapper aimed for a smooth transition to
openscenegraph.

That vector code also includes an improoved geodetic conversion routine I
have found some time ago published in the 'journal of geodesy' which avoids
iterative computations for that purpose.

Also the geodetic position class is more typesafe and unitsafe than the
Point3D currently is.

That part is relatively old and in use in my local trees for several months
now.
