"
The generating reader is a reader which converts a functor returning
mutation fragments to a mutation reader.
We currently have 2 generating reader implementations: one operating
with a v1 functor and one with a v2 one. This patch-set converts the v1
functor based one to a v2 reader, by adapting the v1 functor to a v2
functor and reusing the v2 reader implementation.
Tests are also added to both variants.
Tests: unit(dev)
