      3. The class reads the hdu of each FITS, the size of each frame must match the original frame, if not, abort and inform the user.
      4. Ignore the EXPOSURE (time in milliseconds) differences for now. We need to compensate for differences by employing different methods of extrapolation later. 
      5. void combine(int mode); mode is either FITS_AVERAGE or FITS_MEDIAN.
      6. void subtract(unsigned int * img1, unsigned int * img2); we know numOfPixels already.
      7. void divide(unsigned int * img1, unsigned int * img2); we know numOfPixels already.*/
