Contiguous Integration and Code Formatter

[omegaga]

Glad to see GraphView is getting noticed to more people now! However, now that we have published our code in open source community, we will have to pay more attention to our code style and quality. Although our code is mainly a research prototype, we still need a mechanism to do some testing and checking, esp. for a system project like this.

It would be great if we can have a CI integrated into our project, which can run unit tests and style checker automatically whenever we have a new commit. Jenkins and Travis CI would be two greet options. This style checker will also be great to help us clean up our code.
