unittesting and continuations intergration

We need some unittests, I will write a few and try to run it on travisci.

#9 adds a first unittest. I am not sure though how to integrate this with travisci since we need an ssh server running and travis doesn't have that..

@rjrhaverkamp I have done the travis part and integrated the first test case with it. It will also check the code for PEP8 guidelines. Let me know your throughs.

I am so confused.. I wrote some more tests, see #18 but code coverage decreased.. 😖

This is fixed, issue was coverage files were not getting combined. Fixed in 9a42548

@rjrhaverkamp Few unit test ideas:

• Unit test using password, call ssh method directly using password. we can use another environment variable of password in travis file.
• main method validation using key and password both.
• Validation tests for key, password and username validation.

Thanks! Good ideas, I think the validation tests shouldn't be too hard.

We should look into pytest and tox for testing. That will make it easier and more standardised.

@dvopsway If you look at the screenshot, you see the code that isn't covered by tests. But it is impossible to test that code..

any ideas?
