[HOT] Tech WG - tasking manager - workflow branch

[Daniele Venzano]

I like this idea a lot. Having a validation system based on some kind
of voting. I think it could work well.

As Theodin says, we could have users that look at a tile and say "looks
good to me". Once you have three of these, you mark the tile as
validated.
You can also have "special" users that can invalidate and/or validate in
one click.

There could be also a per-task configurable threshold. So for tasks
with many users the task admin can put an higher number of votes to
validate and have a better confidence in the data. Other tasks could
have just one vote needed, reverting to how the system currently works.

About invalidation: I am not so confident that a down-voting system
could work. I would prefer that an experienced mapper has the ability to
invalidate if he sees something wrong.
Some experimentation could be needed.

Thanks,
Daniele
