First try at travis setup.
Trying to correct .travis install key.
Replace a tab with spaces in .travis.yml
Adding script key to travis.yml.
Fixed EOF in .travis.yml ... again.
Removed the numpy step from the install key because it's already satisfied by the virtualenv an added a stwcs line.
Merge pull request #101 from STScI-Citizen-Science/travis


This commit is kinda wonky but just bear with it in the interests of getting Travis up and running.
