For a select_multiple question allow only a maximum number of answers.

I'm looking at your code an trying to implement a select_multiple question, where you could select, lets say, three out of four choices. Could you point me to where in the code that could be implemented? @Pierre-Sassoulas

In model it's defined here: https://github.com/Pierre-Sassoulas/django-survey/blob/master/survey/models/question.py#L57
In form it's here: https://github.com/Pierre-Sassoulas/django-survey/blob/master/survey/forms.py#L24

It's probably possible to override the default class from Django :)
