  \brief Interface for the Servolens lens attached to the camera fixed on the 
  Afma4 robot.

  The code below shows how to manipulate this class to get and modify
  the position of the focal lens.

  \code
#include <iostream>
#include <visp/vpServolens.h>

int main()
{
  // Open the serial device to communicate with the Servolens lens
  vpServolens servolens("/dev/ttyS0"); 

  // Get the current zoom position
  unsigned zoom;
  servolens.getPosition(vpServolens::ZOOM, zoom);
  std::cout << "Actual zoom value: " << zoom << std::endl;

  // Set a new zoom value
  servolens.setPosition(vpServolens::ZOOM, zoom+1000);  
}
  \endcode
