Some cosmetic changes were made in the pipeline to prepare it for the
public release. In particular the following:

 - The `README' file was updated to be more clear and follow the same
   format as that of the photometry and astrometry pipeline (with the
   necessary corrections).

 - A `configure' script was added to greatly simply the processing of
   setting the input directories. The version controlled
   `DIRECTORIES.mk.in' file is now the base file. After running
   `./configure', a copy of it is put into `DIRECTORIES.mk' and an
   editor is opened so the user can set them easily.

 - The acceptable version of Gnuastro was changed from the unofficial
   and not-released version `0.2.52-f620' to `0.2.51-bc56-bugfix'. The
   only necessary correction was in a single file
   (`bin/mkcatalog/upperlimit.c'), so that file is now included in
   this pipeline to allow easy correction to the main Gnuastro branch
   if it is necessary to fetch this snapshot from Gnuastro's history
   directly. The instructions to do this are available in `README'.

 - In the version of the pipeline that was used to publish the paper,
   we had 13 extra objects that were not specificly detected by
   ORIGIN, making a total of 173 objects. However, only 160 objects
   have an ORIGIN-only flag in the final catalog (the extra objects
   were not used). So to keep things clean, the 13 extra objects are
   removed from the input table and the whole input table is now
   available in the repository. The file
   `reproduce/input/input-positions.txt' also describes how to
   generate this table from the released catalog. Since the input
   catalog is no longer a user-specified parameter, the file and
   variable names were changed to an all-small-caps format.

 - A small Perl `flock' script is added to the pipeline so if it is
   not available on the system, it can easily be copied from here.

 - One of the objects (MUSE ID 6512) that was mistakenly classified as
   `RP' (existing/present in Rafelski catalog) is now correctly
   classified as `RC'. The reason was an visual mistake: there was
   another brighter source near the large galaxy, so I had thought
   that is the main target. But zooming into the FITS file, I noticed
   that the main object of interest is actually part of the brigher
   galaxy.

 - A typo of `Ns' (instead of `NS') was corrected in the
   classification table. To avoid such mistakes the checks of the
   codes are now in an `if-else' conditional, not independent `if's.

 - To allow more clarity in the percentages of the classification,
   they are now reported to two decimals in the internal description.

 - The demonstration cutout codes were corrected for the new list
   (that is now only 160 objects, instead of the old 173).

 - Removed the extra `subsection.tex' file since the the contents of
   the main PDF weren't included in the main paper either.

 - Removed the version number from the final output files, so they
   aren't need-lessly created on every change in the Git repo. The
   version is alrady present within the files.

 - Added section describing the small differences between the
   classsifications of this pipeline and those reported in the paper.

 - Corrected the copyright information and my email.
