0.11.0 - Better initialization orders in generated `__init__`

Fixed fields initialization order in generated constructor methods:

• the order is now the same than the order of appearance in the class (and not reversed as it was). Fixed #36.
• the above is true, even in python < 3.6. Fixed #38
• the order now takes into account first the ancestors and then the subclasses, for the most intuitive behaviour. Fixed #37.

See documentation page for details.
