/** Remote logging interface. The twin of XLogger. This interface will do the
    remote communication. Differences compared with XLogger:

    getLogger() is omitted as createInstance will suffice here.
    No need to obey to the java API here.

    getName() and isLoggable() are added here just in case.
    Normally these two can be handled by XLogger without using this interface.

    logp() contains an additional parameter "thread" which enables the server
    to display the client thread of this call

    addPropertiesChangeListener() is used to register a call back with the server.
    This enables ther server to communicate any changes in the configuration
    to the client. The client can use this info to do some prechecks thus
    avoiding unneccessary remote calls.
