Implemented an instance of
Lookup nat (St * option (L * St)) (trace St L)for an easy access toith transition in a trace.An example usage included in this PR is a fact that in an
mtrace_validtrace every pair of adjacent states is related by the model transition relation.Also added
Lookup nat St (trace St L)andLookup nat L (trace St L)to access specifically states or labels. The lemmapred_at_trace_lookupexpresses the correspondence between these lookups and existingpred_atpredicate.
