/** Function: log
* User overrideable logging function.
*
* This function is called whenever the Strophe library calls any
* of the logging functions. The default implementation of this
* function does nothing. If client code wishes to handle the logging
* messages, it should override this with
* > Strophe.log = function (level, msg) {
* > (user code here)
* > };
*
* Please note that data sent and received over the wire is logged
* via Strophe.Connection.rawInput() and Strophe.Connection.rawOutput().
*
* The different levels and their meanings are
*
* DEBUG - Messages useful for debugging purposes.
* INFO - Informational messages. This is mostly information like
* 'disconnect was called' or 'SASL auth succeeded'.
* WARN - Warnings about potential problems. This is mostly used
* to report transient connection errors like request timeouts.
* ERROR - Some error occurred.
* FATAL - A non-recoverable fatal error occurred.
*
* Parameters:
* (Integer) level - The log level of the log message. This will
* be one of the values in Strophe.LogLevel.
* (String) msg - The log message.
