\a main function of the test program. It fulfills the following operations, in order:
- initialize Gt and GnomeVFS;
- loads atomic radii (the 3D viewer needs the van der Waals radii).
- build the widow embedding the sample GtkChem3DViewer.
- build the GtkChem3DViewer with either a file from the command line or the default
methane.xyz provided with the sources.
- shows everything and enter \a gtk_main().
