ImportError: cannot import name ForcedError

[renner]

Hello,

I could be missing something, but I keep on getting the above ImportError when just running a simple example. Actually just import Marshmallow is enough:

>>> from flask_marshmallow import Marshmallow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/renner/devel/git/ticklist-flask/flask/lib/python2.7/site-packages/flask_marshmallow/__init__.py", line 21, in <module>
    from . import fields
  File "/home/renner/devel/git/ticklist-flask/flask/lib/python2.7/site-packages/flask_marshmallow/fields.py", line 16, in <module>
    from marshmallow.exceptions import ForcedError
ImportError: cannot import name ForcedError
>>>

Thanks for reporting, @renner . The error you are seeing is due to an incompatibility with marshmallow>=2.0.0a. I've opened an issue here: #16. I will fix this and release the patch within the next day or two.

@renner Version 0.5.1 is now on the PyPI, and it is compatible with marshmallow 2.0

That is very good @sloria, thanks for fixing this so quickly!
