Automatic testing

[Mathieu Clabaut]

Hello,

 I've ported most of the scripts of the "test" directory into a py.test script. See pull request 65 (https://github.com/SimonAlfie/fabricate/pull/65).

 Some of the tests do not pass (mostly for documented issues).

 I also put up a TravisCI account on my repository so as to have continuous integration (for several python versions) and a report badge on the github main page (See : https://github.com/matclab/fabricate/tree/pytest. The badge links to the test reports)

 I will now probably move the py.test fixtures in a conftest.py file so as to allow people to write more test files.

 Hope this help.

Best regards,

-Mathieu
