Revision: 14391

Author: judecn

Log Message:
-----------
Created the SceneBuilder API, which creates and flyweights OSG nodes, geometry data, and textures, and modified the proof-of-concept scene to
demonstrate the new API in action. The three metal cows in the scene are really just one node that has been encapsulated within three different
transformation nodes, and the two parallel ground planes are really just one geometry and one texture encapsulated within two different geodes.
Also, added an INSTALL file.

+BZWorkbench Installation Notes
+------------------------------
+
+To compile BZWorkbench, just cd into Debug and run "make all".
+Aside from usual dependency on a GNU build environment, BZWorkbench has
+the following library and source dependencies:
+
+ (*) FLTK 1.1.7
+ (*) OpenSceneGraph 2.0
+ (*) OpenGL 1.4
+
+Currently, BZWorkbench only runs on UNIX platforms (including Mac OS X),
+and has only been tested by the developer on Debian GNU/Linux 4.0. It
+might run on Cygwin; but you're on your own there.
+
+To run BZWorkbench, you should either copy, move, or symlink the
+bzworkbench binary to the root of the source tree. Otherwise, it will
+crash (i.e. it expects to find certain files relative to the root of the
+source tree, rather than relative to the Debug directory). Given that
+this project is still in its infancy, there is no "make install" command.
