The --molecule flag was defined but never wired up - the slingMolecule
variable was set by the flag parser but never read by any code path.
Users should use --on instead, which is fully implemented:
gt sling <formula> --on <bead> <target>
The --on flag properly instantiates the formula (cook + wisp + bond)
and applies it to the target bead before slinging.
Keeping --on as the canonical way to apply formulas to beads since it's
actually wired up and working. The --molecule flag can be re-added later
if a different argument order is desired.
