 Methods
 -------
-1. `on(event: String, callback: ((data: [AnyObject], ack: SocketAckEmitter?) -> Void))` - Adds a handler for an event. Items are passed by an array. `ack` can be used to send an ack when one is requested. See example.
-2. `onAny(callback:((event: String, items: AnyObject?)) -> Void)` - Adds a handler for all events. It will be called on any received event.
-3. `emit(event: String, _ items: AnyObject...)` - Sends a message. Can send multiple items.
-4. `emit(event: String, withItems items: [AnyObject])` - `emit` for Objective-C
-5. `emitWithAck(event: String, _ items: AnyObject...) -> (timeoutAfter: UInt64, callback: (NSArray?) -> Void) -> Void` - Sends a message that requests an acknowledgement from the server. Returns a function which you can use to add a handler. See example. Note: The message is not sent until you call the returned function.
-6. `emitWithAck(event: String, withItems items: [AnyObject]) -> (UInt64, (NSArray?) -> Void) -> Void` - `emitWithAck` for Objective-C. Note: The message is not sent until you call the returned function.
-7. `connect()` - Establishes a connection to the server. A "connect" event is fired upon successful connection.
-8. `connect(timeoutAfter timeoutAfter: Int, withTimeoutHandler handler: (() -> Void)?)` - Connect to the server. If it isn't connected after timeoutAfter seconds, the handler is called.
-9. `close()` - Closes the socket. Once a socket is closed it should not be reopened.
-10. `reconnect()` - Causes the client to reconnect to the server.
-11. `joinNamespace()` - Causes the client to join nsp. Shouldn't need to be called unless you change nsp manually.
-12. `leaveNamespace()` - Causes the client to leave the nsp and go back to /
-13. `once(event: String, callback: NormalCallback)` - Adds a handler that will only be executed once.
