+<P>
+This is the main class of ZooKeeper client library. To use a ZooKeeper
+ service, an application must first instantiate an object of ZooKeeper class.
+ All the iterations will be done by calling the methods of ZooKeeper class.
+ The methods of this class are thread-safe unless otherwise noted.
+ <p>
+ Once a connection to a server is established, a session ID is assigned to the
+ client. The client will send heart beats to the server periodically to keep
+ the session valid.
+ <p>
+ The application can call ZooKeeper APIs through a client as long as the
+ session ID of the client remains valid.
+ <p>
+ If for some reason, the client fails to send heart beats to the server for a
+ prolonged period of time (exceeding the sessionTimeout value, for instance),
+ the server will expire the session, and the session ID will become invalid.
+ The client object will no longer be usable. To make ZooKeeper API calls, the
+ application must create a new client object.
+ <p>
+ If the ZooKeeper server the client currently connects to fails or otherwise
+ does not respond, the client will automatically try to connect to another
+ server before its session ID expires. If successful, the application can
+ continue to use the client.
+ <p>
+ Some successful ZooKeeper API calls can leave watches on the "data nodes" in
+ the ZooKeeper server. Other successful ZooKeeper API calls can trigger those
+ watches. Once a watch is triggered, an event will be delivered to the client
+ which left the watch at the first place. Each watch can be triggered only
+ once. Thus, up to one event will be delivered to a client for every watch it
+ leaves.
+ <p>
+ A client needs an object of a class implementing Watcher interface for
+ processing the events delivered to the client.
+
+ When a client drops current connection and re-connects to a server, all the
+ existing watches are considered as being triggered but the undelivered events
+ are lost. To emulate this, the client will generate a special event to tell
+ the event handler a connection has been dropped. This special event has type
+ EventNone and state sKeeperStateDisconnected.

+<DD>Create a node with the given path. The node data will be the given data,
+ and node acl will be the given acl.
+ <p>
+ The flags argument specifies whether the created node will be ephemeral
+ or not.
+ <p>
+ An ephemeral node will be removed by the ZooKeeper automatically when the
+ session associated with the creation of the node expires.
+ <p>
+ The flags argument can also specify to create a sequential node. The
+ actual path name of a sequential node will be the given path plus a
+ suffix "i" where i is the current sequential number of the node. The sequence
+ number is always fixed length of 10 digits, 0 padded. Once
+ such a node is created, the sequential number will be incremented by one.
+ <p>
+ If a node with the same actual path already exists in the ZooKeeper, a
+ KeeperException with error code KeeperException.NodeExists will be
+ thrown. Note that since a different actual path is used for each
+ invocation of creating sequential node with the same path argument, the
+ call will never throw "file exists" KeeperException.
+ <p>
+ If the parent node does not exist in the ZooKeeper, a KeeperException
+ with error code KeeperException.NoNode will be thrown.
+ <p>
+ An ephemeral node cannot have children. If the parent node of the given
+ path is ephemeral, a KeeperException with error code
+ KeeperException.NoChildrenForEphemerals will be thrown.
+ <p>
+ This operation, if successful, will trigger all the watches left on the
+ node of the given path by exists and getData API calls, and the watches
+ left on the parent node by getChildren API calls.

+ If a node is created successfully, the ZooKeeper server will trigger the
+ watches on the path left by exists calls, and the watches on the parent
+ of the node by getChildren calls.
