Landon Curt Noll 0fa01fd744 add title and abstract to .entry.json and index.html files
We add an initial "_title_" and "_abstract_" to all entry `.entry.json` files.

The `bin/csv2entry.sh` tool reads the `summary.csv` file and
loads the "_title_" and "_abstract_" to entry `.entry.json` files.

Changed `bin/csv2entry.sh` VERSION from "1.3 2024-09-23"
to "1.4 2024-09-27".

Perform `make csv2entry` to perform the above and test under macOS.

The `bin/cvt-submission.sh` tool adds "_title_" and "_abstract_" to the
.entry.json based on the `.info.json` file.

Changed `bin/cvt-submission.sh` VERSION from "1.2 2024-09-23"
to "1.3 2024-09-27".

The `bin/entry2csv.sh` tool forms the `summary.csv` file
based on the "_title_" and "_abstract_" fields found in .entry.json files.

Changed `bin/entry2csv.sh` VERSION from "1.3 2024-09-23"
to "1.4 2024-09-27".

Perform `make entry2csv` to perform the above and test under macOS.

Added `-H` and `header=with-header-3` to the `bin/md2html.cfg`
for the configuration entry for `[12][0-9][0-9][0-9]/*/README.md`.

Changed `bin/md2html.sh` VERSION from "1.6 2024-08-17"
to "1.7 2024-09-27".

All entry `index.html` files now list the "_abstract_" in a new
`<h3>abstract</h3>` header.

Changed `bin/subst.entry-index.sh` VERSION from "1.6 2024-09-23"
to "1.7 2024-09-27".

Removed `summary.csv`.

Added `summary.csv` and `summary.numbers` to `.gitignore`.
Sorted the result with `bin/sgi.sh`.

Perform `make quick_www` to perform the above and test under macOS.

Perform `make www` to perform the above and test under macOS.

<p>An alternate version of this entry, <a href="https://github.com/ioccc-src/temp-test-ioccc/blob/master/2015/endoh4/prog.alt.c">prog.alt.c</a>, is provided.
This alternate code does not contain improvements suggested by <a href="../../authors.html#Gil_Dogon">Gil
Dogon</a>; it is the author’s original entry.</p>
<h3 id="alternate-build">Alternate build:</h3>
<pre><code> make alt</code></pre>
<h3 id="alternate-use">Alternate use:</h3>
<p>Use <code>prog.alt</code> as you would <code>prog</code> above.</p>
<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>For this one liner it is best to avoid prime numbers. The output groups
factors in the x-y dimensions. How many factors can be represented before you
run out of command line argument space? How could you modify the program to
experiment with numbers that have more or larger factors?</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<p>Visual factorization 1-liner. Try:</p>
<pre><code> gcc -o prog prog.c
./prog @
./prog @ @
./prog @ @ @
./prog @ @ @ @
./prog @ @ @ @ @ @
./prog @ @ @ @ @ @ @ @
./prog @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @</code></pre>

<p><a href="https://github.com/ioccc-src/temp-test-ioccc/blob/master/2015/endoh4/prog.alt.c">prog.alt.c</a> is the original version that I submitted. <a href="../../authors.html#Gil_Dogon">Gil
