/*! Logs messages to the importer logfile and the console

    @param  verbosity    the verbosity of the message
    @todo   Build a dedicated log class that can be instantiated (so the importer can have its own)
            Let this log class write to file etc.
            Don't use printf anymore, its c. (c++11 has to_str, else we have to work with ss (ugh...))
            I only used printf here because it allows me to combine a string with different variables
            in only one line and I don't have an easy way to do this in c++0x. Again c++11 would be easy.
