python importing conflicts

[wdeconinck]

After putting the PYTHONPATH to the coolfluid/dso directory,
and in python calling
import numpy,
a conflict appears:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/__init__.py", line 136, in <module>

    from unittest import TestCase
ImportError: cannot import name TestCase

The reason is the file "unittest.py" inside the coolfluid/dso dir, that was added recently. @barche, do you know a way around this?

[barche]

Yes, let's just remove our unittest.py, and move the functions to coolfluid.py, preferably as members of a unittest class. I was unaware that we had this, I think this also explains why ipython doesn't start anymore with the dso dir in the PYTHONPATH

[wdeconinck]

I was also unaware. It seems to be Vivian's good work. We should indeed try to find a solution for this in a more pythonic way, including classes, namespaces etc.

[wdeconinck]

In the latest commit I renamed the unittest.py file to check.py to solve this temporarily

[barche]

OK, good, this might not even need to be so temporary, we just need to come up with a design for the part of our module that will be implemented in python
