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).

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.
