module Make:
Parameters: 

val analyze : (G.V.t > A.data) > A.g > G.V.t > A.data
analyze f g
computes the fixpoint on the given graph using the
work list algorithm. Beware that a misconstructed Analysis will
not terminate! f
is used to create the initial analysis
data. The function returned is a map to see what data was computed
for which node.
Beware of applying function analyze
partially, to arguments
f
and g
only. The result is a function that is to be used to query
the result of the analysis.
