This module uses a local build of the Astrometry.net software in order to
compute the astrometric solution of the input FITS files, saving the new files,
containing the WCS header, to the output directory. This is, in essence, a mere
simple interface to solve-field, Astrometry.net's command-line high-level user
interface, which must be present in PATH. Keep in mind that for Astrometry.net
to work it is also necessary to download the index files.
