Surveys wedding/event seating tools currently available: most are
pure drag-and-drop editors with no optimization algorithm, while a
smaller group (notably PerfectTablePlan) uses the same genetic
algorithm / scoring approach as this project. Documents pricing
patterns and identifies the gap this project could fill: a
web-native SaaS with real optimization and a German/EU-focused,
GDPR-friendly hosting story, which none of the surveyed competitors
currently offer together.

Documents a 5-milestone path (foundation, MVP web tool, variant
generation, accounts/persistence, monetization) to turn the
existing GA seating solver into a hosted service for wedding/event
seating, including effort estimates, GDPR considerations once real
guest data is stored long-term, and why a freemium/one-time-payment
model fits this use case better than advertising.

Sitzplatzverteilung.alsSVG() (libs/Strukturdaten.py) draws tables as
white circles and people as colored circles inside their table's
circle, colored by group membership. Table radius is derived from
the number of seats so all person-circles fit without touching; the
table-to-table grid spacing is derived from the largest table radius
so tables never overlap regardless of their Koordinaten values.
libs/platz.py gains a --tosvg switch that writes
<indir>/Sitzplatzverteilung.svg alongside the existing text/CSV
output.
The three unittest scenarios now each write their rendering to
doc/images/, and doc/docu_tests.md explains the three configurations
and what each test actually verifies (including why the "split
groups land on true neighbor tables" property only holds for a
specifically chosen seed in the circle scenario, not in general).

and runs python -m unittest discover against tests/.

Covers three concrete seating layouts to exercise the GA's group
placement and splitting logic:
- three tables chained pairwise (2 seats each), three couples ->
no group gets split, optimal score of 0.
- four tables in a line (2 seats each), two groups of four -> each
group ends up split across one contiguous table pair (T1+T2 or
T3+T4), never mixed across the middle seam.
- six tables in a circle (2 seats each), four groups of three ->
each group is split exactly once (2+1), since no table has three
seats; with the fixed seed the split pairs are also true circle
neighbors.
Also documents how to run the suite in README.md, including the
PYTHONPATH workaround needed when a stray global env var shadows
the stdlib "tests" package name with an unrelated project's tests.

Adds a comment header explaining what e/s/S/m/j/z mean in the
Abfolge sequence, referencing the corresponding Farm actions in
libs/ga.py.

Replace Python 2-only constructs throughout libs/: print statements,
ConfigParser -> configparser, sets.Set -> builtin set, string.split ->
str.split, xrange -> range, dict.has_key()/.iteritems() -> in/.items(),
old-style raise Exception, "msg" syntax, and __cmp__ -> __eq__/__lt__
via functools.total_ordering (Python 3 dropped cmp()/__cmp__, which
max()/.sort() rely on). Also cleaned up mixed tab/space indentation
that Python 3's stricter tokenizer rejects.
Fixed two latent bugs that only surfaced once end-to-end runs were
possible under Python 3's stricter error handling:
- HandleBestellung() compared G.Anzahl (a bound method) to an int
instead of calling G.Anzahl() - silently "worked" under Python 2's
permissive cross-type ordering, raises TypeError under Python 3.
- LeuteAllein() raised KeyError for VIP-group members, who are never
added to the regular Gruppen container; now skips people with no
group entry instead of crashing.
Verified end-to-end: bin/platz.sh --indir work/test1 and --indir
work/test2 (VIP group included) both run to completion and produce
correctly formatted output.

Tischedatei, XMLdatei_Bestellung, AusgabeTischePersonen and
AusgabePersonTisch are no longer configured in platz.cfg. Instead,
platz.py now requires a --indir <dir> command-line switch pointing
at a directory that must contain tische.ini and bestellung.xml, and
into which TischePersonen.txt/PersonenTische.csv are written - e.g.
work/test1 or work/test2. This makes it trivial to run against
different guest lists without editing platz.cfg. platz.bat/platz.sh
forward extra arguments so --indir can be passed through.

platz.bat/platz.sh now derive PLATZ via setenv instead of hardcoded
paths, matching the Standard Programm Template already applied to
setenv/install_py/activate_venv/get_cmd. Added the missing .sh
counterparts to those .bat scripts, an empty requirements.txt for
install_py to install (project only uses the stdlib), and ignore
entries for .venv/, out/, .vscode/, *.swp.
