Issue #69 Support building with Eclipse tycho

Made tests pass.
AFAIK Tycho only supports JUnit, not TestNG. So switched to JUnit.
Added support for continuous integration via Travis CI.

CFGBuilder.java:
Fixed a compilation failure.

*Test.java:
Ensured tests compile and pass.

.travis.yml: ADDED

README.MD:
Added Travis CI button to show to build status
