+Each peer has one `MConnection` (multiplex connection) instance.
+
+__multiplex__ *noun* a system or signal involving simultaneous transmission of
+several messages along a single channel of communication.
+
+Each `MConnection` handles message transmission on multiple abstract communication
+`Channel`s. Each channel has a globally unique byte id.
+The byte id and the relative priorities of each `Channel` are configured upon
+initialization of the connection.
+
+There are two methods for sending messages:
+ func (m MConnection) Send(chID byte, msgBytes []byte) bool {}
+ func (m MConnection) TrySend(chID byte, msgBytes []byte}) bool {}
+
+`Send(chID, msgBytes)` is a blocking call that waits until `msg` is
+successfully queued for the channel with the given id byte `chID`, or until the
+request times out. The message `msg` is serialized using Go-Amino.
+
+`TrySend(chID, msgBytes)` is a nonblocking call that returns false if the
+channel's queue is full.
+
+Inbound message bytes are handled with an onReceive callback function.
