Update CIQ extension to use mixbox. Fix #260.

[gtback]

I added a basic test to verify the extension works, but not much more than that. The test is pretty fragile, but better than nothing.

@bworrell: If you're OK with this, go ahead and merge. Otherwise, let me know what else you were planning as part of #260.

Code quality remained the same when pulling b2cf273 on CybOXProject:ciq into c889ade on CybOXProject:master.

Bah! I can fix the errors on py32, py33, py34 by using six.StringIO, but I don't know what to do about RHEL6.

• Skip the test entirely on in rhel6?
• Bump the required version of LXML package-wide?

Thoughts?

Maybe for now we just exclude the test in rhel6 and see what comes of #266. We might be able to fix this by dropping lxml.

Thanks, @bworrell. I ended up using some hackery to skip the test. I couldn't just use skipTest() without more hackery.

Haha, I figured you were going to use the --exclude option for nose in our tox.ini file. Something like:

[testenv:rhel6]
basepython=python2.6
commands =
    nosetests cybox --exclude="ciq_test.py"
deps =
    lxml==2.2.3
    mixbox>=0.0.7
    python-dateutil==1.4.1
    nose

I'm not sure if that'd work at all but it's kinda how i was thinking about skipping it for rhel6.

Oh, I didn't know about that. Oops.
