* 3D vector with automatic notification on change.

* This implementation of a 3D vector along with all the sibling and helper
* classes in the geometry section, try to strike a balance between clean code,
* ease-of-use and speed. Fields are public and most methods are designed to
* give the impression of a very intelligent and capable structure. Heavier
* code such as intersections is encouraged to be added externally instead
* of here.
*
* The vector is a member of the geometry classes next to CMatrix and CRotation
* @see CMatrix
