    //! \class ActiveTextLoggerComponentImpl
    //! \brief Active text logger component class
    //!
    //! Similarly to the PassiveTextLogger, this component takes log texts
    //! and prints them to the console, but does so from a thread to keep
    //! consistent ordering.  It also provides the option to write the text
    //! to a file as well.

            //!  \brief Component constructor
            //!
            //!  The constructor initializes the state of the component.
            //!
            //!  Note: Making constructor explicit to prevent implicit
            //!  type conversion.
            //!
            //!  \param compName the component instance name

            //!  \brief Component initialization routine
            //!
            //!  The initialization function calls the initialization
            //!  routine for the base class.
            //!
            //!  \param queueDepth the depth of the message queue for the component
            //!  \param instance: instance identifier. Default: 0.

            //!  This is to create an optional log file to write all the messages to.
            //!  The file will not be written to once the max size is hit.
            //!
            //!  \param fileName The name of the file to create.  Must be less than 80 characters.
            //!  \param maxSize The max size of the file
            //!  \param maxBackups The maximum backups of the log file. Default: 10
            //!
            //!  \return true if creating the file was successful, false otherwise
