healpix fits files are a "special" type of FITS file from kst's perspective.  
The healpix datasource claims ownership of the file instead of the LFIIO 
datasource (which normally reads table extensions).

To plot the healpix data as a map, one uses the "-z" command line option.

The command below suggests that you wish to plot the raw pixel data on an x-y 
plot (i.e. pixel value vs. pixel index), correct?  This is not currently 
supported by the healpix datasource.  The datasource currently returns either 
a cartesian projection of a map as a matrix, OR one of the polarization 
pseudo vector coordinates.  Vector fields won't be supported until the new 
rendering system is in place.

Do we want the healpix datasource to be able to return raw pixel values?
