    Fit a function to camera pointing
  
 
          Description
        
    This program requires a cube be initialized with "spiceinit".  It will
    then look at the InstrumentPointing table for the cube and use a least
    square solution to compute a fit of the right ascension, declination,
    and twist to a parabola.  This should reduce "noisy"
    pointing data.  To restore the original pointing just rerun "spiceinit".
     
     Note that this program should be used on line scan cameras.  It will not work
     on framing cameras.

      Added check to see if cube has existing polygon, if so delete it.

      Added code to write InstrumentPointing keyword value as table in kernels 
      group in case the kernels are not already attached.
