Virtual member functions

• virtual void set_name(char *) - used to change or set the name of the molecule. Called during the create phase of molecule construction.
• virtual void create_cmdlist(void) - regenerates the display list, which contains the list of primitive drawing commands necessary to draw the object.
• virtual int create(void) - the version of create for DrawMolecule ... this is called by derived classes after they have read in and initialized the molecule. The DrawMolecule version of create will then call the BaseMolecule's create routine, and finally then construct the initial version of the display list.
• virtual void prepare(DisplayDevice *) - provided since this is a Displayable object. This determines if the display list needs to be reconstructed, and if so it does the reconstruction.
• virtual int add_rep(AtomColor *, AtomRep *, AtomSel *) - requests for a new representation to be made, using the given objects to describe what the representation should be. Returns success.
• virtual int change_rep(int, AtomColor *, AtomRep *, AtomSel *) - changes the Nth representation to use the new settings specified in the given objects.
