Integration of Tomas Hrasky's port of basic GLU NURBS functionality

from C++ to Java, plus example applications, done as part of his
Bachelor of Science degree at the University of Hradec Králové,
Faculty of Informatics and Management.

Current state of code is documented in
src/classes/com/sun/opengl/impl/nurbs/README.txt.

Example applications require Java 1.5 and are not currently built by
default. Specify -Djogl.nurbs=1 during jogl-demos build with a 1.5
javac on the PATH to build them. Dependent jars are copied to build
output directory.

Deleted old partially-complete GLU NURBS port.
