/**
 * A method annotated with this will be called when a remote network connection is offered.
 * The method should have two parameters, of types Map<String,String> and {@link Side}. It should return a boolean
 * true indicating that the remote party is acceptable, or false if not.
 *
 * <p>
 * When the method is invoked, the map will contain String keys and values listing all mods and their versions present.
 * The side represents the side of the remote party. So if you're on the server, it'll be CLIENT, and vice versa.
 *
 * <p>
 * This method will be invoked both when querying the status of the remote server, and when connecting to the remote server.
 *
 * <p>
 * <strong>NOTE: the server will not be setup at any point when this method is called. Do not try and interact with the server
 * or the client in any way, except to accept or reject the list of mods.</strong>
