Import cornice fails because colander is not installed

[ottokruse]

When importing cornice an import error is raised. Apparently colander is now a dependency (is that correct?), but it is not listed as a dependency by cornice.

File "/usr/local/lib/python3.5/site-packages/cornice/init.py", line 10, in
from cornice.service import Service # NOQA
File "/usr/local/lib/python3.5/site-packages/cornice/service.py", line 6, in
from cornice.validators import (
File "/usr/local/lib/python3.5/site-packages/cornice/validators/init.py", line 5, in
from cornice.validators._colander import (
File "/usr/local/lib/python3.5/site-packages/cornice/validators/_colander.py", line 4, in
import colander
ImportError: No module named 'colander'

Thanks for the feedback!
It's a bug! Colander shouldn't be a dependency.

Sure thing. Great that you guys are working on this software

I will add a new travis job to make sure everything works without colander.
