bumped astropy to 0.4.0

I tried installing on a machine with astropy 0.3.0 (the current version in the Ubuntu 14.04 repositories).

When I try importing I get the following error:

>>> import sncosmo
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ufein/.virtualenvs/sncosmo-test/local/lib/python2.7/site-packages/sncosmo/__init__.py", line 124, in <module>
    from astropy.config import ConfigItem, ConfigNamespace
ImportError: cannot import name ConfigItem

ConfigItem does not exist before astropy 0.4.0, so I the requirement should be bumped to the version. I quickly verified that it work with that version in separate virtualenvs.

Unless I'm mistaken pip-requirements is all that needs to be changed.

Yep, you're right. The minimum astropy version should now be v0.4.0.

You should be able to install an older version of sncosmo (maybe v0.4?) which will work with astropy v0.3.

Thanks!
