    Creates a new instance.
    
    Parameters:
    
    webSocketURL - URL for web socket communications. e.g "ws://myhost.com/mypath". Subsequent web socket frames will be sent to this URL.
    
    version - Version of web socket specification to use to connect to the server
    
    subprotocol - Sub protocol request sent to the server.
    
    allowExtensions - Allow extensions to be used in the reserved bits of the web socket frame
    
    customHeaders - Map of custom headers to add to the client request
    
    maxFramePayloadLength - Maximum length of a frame's payload

    Creates a new instance.
    
    Parameters:
    
    webSocketURL - URL for web socket communications. e.g "ws://myhost.com/mypath". Subsequent web socket frames will be sent to this URL.
    
    version - Version of web socket specification to use to connect to the server
    
    subprotocol - Sub protocol request sent to the server.
    
    allowExtensions - Allow extensions to be used in the reserved bits of the web socket frame
    
    customHeaders - Map of custom headers to add to the client request
    
    maxFramePayloadLength - Maximum length of a frame's payload
    
    performMasking - Whether to mask all written websocket frames. This must be set to true in order to be fully compatible with the websocket specifications. Client applications that communicate with a non-standard server which doesn't require masking might set this to false to achieve a higher performance.
    
    allowMaskMismatch - When set to true, frames which are not masked properly according to the standard will still be accepted
