Issue 206 : Example program cleanup

Item 4) Reorganized directory structure to make the examples a single project rather than a collection of independent apps.

    . All example programs moved under src/classes, and all are now in a subpackage of org.jdesktop.j3d.examples.

    . All resource files (geometry, images, audio) moved under src/resources

    . ant script now exists only at top level

    . Created netbeans project file for NetBeans IDE
