Setup Travis CI #15
Description
We should setup CI so that we can make sure that tests pass before merging PRs and that we're confident the library builds. Travis now covers all three major Tier 1 supported Rust platforms so we can make sure our library works cross platform.
To close:
- Get CI to work on MacOS, Linux, and Windows Travis CI builds
- Have tests run as part of the CI
- Have CI required to pass on stable and optionally warn on beta and nightly to inform of possible breakage
- Set CI to run tests every night on a cron job for the latest master
