discussion - how many packets per level

[nikkolasg]

should have discussion about the two approaches the two nicolas have implemented:

• Each time there is a better signature for a given level, we send this new signature to candidateCount peers. The periodic update only sends the current best signature at each level periodically. This sends a lot of "low quality" signatures but homogeneize all nodes.
• when there is a better signature, it will be sent only during the next iteration of the periodic update to one single peer. Only when there is a full signature, it sends to candidateCount peers. This reduces the load of "low quality" signatures but can produces more heterogeneous signatures between all peers.
