Hi @vasia,
Configurations can be merged if there exists a configuration which
satisfies all configuration constraints. It is left to the algorithm to decide
whether and how to merged the values.
I see the library algorithms as exemplars for and inspiration to Gelly
users.
A `GraphAnalytic` encapsulates accessing computed values via accumulators
after execution. Do you think this functionality could be added to
`GraphAlgorithm`?
