BUG: Removed import nose on top of testing.py script
I'm having this error in master branch:

> > > import pandas
> > > Traceback (most recent call last):
> > >   File "<stdin>", line 1, in <module>
> > >   File "pandas/**init**.py", line 33, in <module>

> > >     import nose
> > > ImportError: No module named nose

this is not necessary; how are you building master?
 I did this:
python setup.py build_ext --inplace

then run:
python setup.py develop

Does pip install pandas will also install nose?
 no...you need to install nose separately (and cython too)
 Okay I might be missing something, but pandas/**init**.py  is importing from pandas.util.testing import debug wouldn't this error out on fresh installs once there's a new release of pandas or nose is part of setup.py requirements?
 hmm...i just looked at my installed version and it IS different; apparently this was added recently
so your PR is good! (and we don't test this on travis....nose is automatically installed)
 can you hook up travis in any event?
 Yeah exactly what I thought and perhaps all developers have nose installed already. Okay let me configure travis I don't now why it's not building since I already hook it on my first commit to pandas.
 if you can try the build (w/o) nose installed would be good as well....good catch!
 thanks for the catch!
