Simulate next inclusion of newcomers
When we look at https://g1-monit.elois.org/willMembers?lg=fr, we always wonder which combinations will be used by Duniter to include new members.
It would be useful to be able to simulate this, by fixing the medianTime value of current block temporarily, not in the DB.
For example, with this command:
duniter gen-next --show --check --at 1495731720
This would simulate the next block with a simulation that our current
medianTime = 1495731720, which is 2017/5/25 19:02:00.
