Fixed size vector.
A constant size (stack-allocated) array which is mainly used for geometry and the corresponding linear algebra work. SVector defines some typedefs and memeber functions which make it more compatible with STL algorithms than the conventional data structure for geoemtric points (struct {float x,y,z};).
Operators are defined in the naive way, i.e. using temporaries, because testing showed that expresseion templates (using PETE) did not provide any improvements, neither with gcc-3.2 nor icc-8.0, perhaps because of the "named return value" optimization which helps to avoid temporaries.
