Logtk_proofs.LLProof_checkSourceTODO: the checker itself.
GOAL: A tiny Tableau-like prover that tries to re-prove each step in a simple way.
type stats = {n_ok : int;steps that were successfully checked
*)n_fail : int;steps that failed
*)n_skip_esa : int;steps skipped because ESA
*)n_skip_trivial : int;steps skipped because they are trivial
*)n_skip : int;steps skipped, not checked
*)}Result for checking only one step
