hello,I am a curator user.I want to ask some questions about connectionTimeout and sessionTimeout. First, I want to know why curator use connectionTimeOut.ConnectionTimeout seems no matter with client.start(). It was used in CuratorZookeeperClient::blockUntilConnectedOrTimedOut,this mean connectionTimeout just used for block some operation until successfully connect or timeout? Second, I want to know how to set connectionTimeouta and sessionTimeout. I see some code comment, and konw sessionTimeout should greater than connectionTimeout. But I don't know why, and I don't know how much longer should sessionTimeout be than connectionTimeout（May be hava something to do with the number of connectString?） And I also want to know , is there any disadvantages if the sessionTimeout shorter than connectionTimeout.
Finally, I want to know is there any good article about curator? I recently read curator code, but I don't know its whole behavior,for example client.start(), so I usually feel quite confused. Thanks!
