For PRCTL*-model checking, we need to extract the maximal state
subformulas in a path formula and substitute those with new
labels, e.g., for
(F P>0.5[...]) & G (s=0 & d=1)
we would get
(F a_1) & G a_2
as the resulting formula, with
a_1 => P>0.5[...]
a_2 => s=0 & d=1
This then allows the recursive computation of the satisfaction sets of
the maximal state subformulas and using those in the computation for
the (simplified) path formula.
