  \brief Quick and dirty class to store RGB unsigned char images 

  This class is a very shallow inmplementation of a 2D RGB image that may 
  only be used to hold tha data and save it. Main purpoise is its use to create 
  some nice and colorfull output.  
  This implementation has nothing to do with T2DImage.
