Use super() instead of the old style call to parent's methods #112
Description
Describe the feature you'd like
Now that we support Python 3.x only, it would be cool to modernize
a little the code.
Two easy points:
- several classes inherent from
object. This is not needed anymore in Python 3.x - calling a method in a parent class like
ParentClass.method(self, args)can be replaced by a call tosuperlikesuper().method(args).
