Computes the stats for opinions and comments
For now, we have created a daemon that walks the database and perform
the computation for all comments and opinions. We could have done it in the
writer process (trli-writed), since it witness any modification to the
database (as performed by end users).
But since this process has a single worker for now, we did not want to slow it down
whenever an opinion or comment is entered.

So using a separate daemon was easy for now. We will optimize this as the database grows.
