is called when a bullet prefixes a tactic, a suggest function
suggesting the right bullet to use on a given proof, together
with a name to identify the behavior. *)

through the command [Set Bullet Behavior "name"].
Two modes are registered originally:
* "Strict Subproofs":
- If this bullet follows another one of its kind, defocuses then focuses
(which fails if the focused subproof is not complete).
- If it is the first bullet of its kind, then focuses a new subproof.
* "None": bullets don't do anything *)
