Add travis integration
Created by: gyscos
This configures travis to build and test termion on the stable, beta and nightly branches.
I updated the rainbow example to work on stable (removed the step_by
feature), which admittedly isn't as pretty. Possible solutions are:
- Wait for
step_by
to be stable before integrating travis - Add conditional to only compile rainbow example on nightly
- Use manual multiplications for now, and update back to
step_by
once it is stable
