What's new:
- Hundreds of bugs hopefully fixed.
- The algorithm with azimuthal normalization has been rewrittren.
- The source finder can now work in parallel (need OpenMP).
- Renewed output files.
- Rings are now placed at n*radsep+radsep/2 by default.
- A user-defined mask can be given as a FITS file.
- Other things I can't remember at the moment.
