new release of Octaviz

There is now finally a new release of Octaviz:

http://octaviz.sourceforge.net/

This release should compile and run using gcc-4.1 with octave-2.1.73
and vtk-5.0.  Some scripts need updating to work well with vtk-5;
expect a newer release shortly.  Since the last release, there are many
new and improved scripts for 3D visualization, including functions to
change axes of figures and add color bars.  Where possible, the syntax
of high-level functions closely match those of Matlab.  Please submit
any bugs.
