**MOMENT! Wird nochmal überarbeitet - ich glaub, ich habs**
Ich hätte mal folgendes "Ergebnis" anzubieten.
Irgendwie beschleicht mich der Verdacht, daß ich die Infotexte zerstört habe.
Vll. hat ja jmd. Lust mal drüberzuschauen.
So, Texte oben/unten sind jetzt beschreibbar; z.B. mit theta für einen 'temperaturabhängigen Widerstand'.
Es ist recht umfangreich geworden, aber es funktioniert.
