fixing the network of the Guess the Correlation example

[amaatouq]

The network should be at the player.round level (i.e., so we can know the structure of the network at each round and track how it changed). At the moment, we don't have that information (i.e., overriding the player.alter list). A simple fix of doing an extra set at the right time on the right object would be related to issue #31 (i.e., onRoundStart ?)

@amaatouq I added onRoundStart, but I didn't go ahead and fixe the "Guess the Correlation" issue itself, I let you try that.

okay fixed it, until we have 'network' object, this will do :D
