Detailed Description

Finds the other players on the wireless network.

get_other_players sends the name of the local user to the other game machines so that they can build up a list of opponents to display in their lobby.

It then receives the names of the other players (sent from the other lobby modules) and sends them to the start_game block. Also, the names are sent to the graphics module as PrintString messages so that they are listed on the lobby screen.
