+/// SimpleRefChannelManager is a type alias for a ChannelManager reference, and is the reference
+/// counterpart to the SimpleArcChannelManager type alias. Use this type by default when you don't
+/// need a ChannelManager with a static lifetime. You'll need a static lifetime in cases such as
+/// usage of lightning-net-tokio (since tokio::spawn requires parameters with static lifetimes).
+/// But if this is not necessary, using a reference is more efficient. Defining these type aliases
