Thanks! Just needs a few minor changes.

Also looks like build is failing because the docs need to be updated.

[sanjayprabhu]

We should just return the .values() so it's not possible to modify this outside of this class.

[sanjayprabhu]

Let's keep the name consistent between the http and the rpc apis. Maybe rename the httpEndpoint to currentPeers?
