	/** Configures throttle parameter for a peer.
	 *
	 *  Unreliable packets are dropped by ENet in response to the varying conditions
	 *  of the Internet connection to the peer.  The throttle represents a probability
	 *  that an unreliable packet should not be dropped and thus sent by ENet to the peer.
	 *  The lowest mean round trip time from the sending of a reliable packet to the
	 *  receipt of its acknowledgement is measured over an amount of time specified by
	 *  the interval parameter in milliseconds.  If a measured round trip time happens to
	 *  be significantly less than the mean round trip time measured over the interval,
	 *  then the throttle probability is increased to allow more traffic by an amount
	 *  specified in the acceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE
	 *  constant.  If a measured round trip time happens to be significantly greater than
	 *  the mean round trip time measured over the interval, then the throttle probability
	 *  is decreased to limit traffic by an amount specified in the deceleration parameter, which
	 *  is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant.  When the throttle has
	 *  a value of ENET_PEER_PACKET_THROTTLE_SCALE, no unreliable packets are dropped by
	 *  ENet, and so 100% of all unreliable packets will be sent.  When the throttle has a
	 *  value of 0, all unreliable packets are dropped by ENet, and so 0% of all unreliable
	 *  packets will be sent.  Intermediate values for the throttle represent intermediate
	 *  probabilities between 0% and 100% of unreliable packets being sent.  The bandwidth
	 *  limits of the local and foreign hosts are taken into account to determine a
	 *  sensible limit for the throttle probability above which it should not raise even in
	 *  the best of conditions.
	 *
	 *  @param peer peer to configure
	 *  @param interval interval, in milliseconds, over which to measure lowest mean RTT; the default value is ENET_PEER_PACKET_THROTTLE_INTERVAL.
