Post from biicode team: C/C++ dev environment with TravisCI, and biicode

Lately we have been uptading the specs so that C and C++ devs that work with Travis CI have clean and up-to-date guidelines of how to build their awesome projects.

This is a guest post from the biicode Team describing how useful Travis CI is in our daily coding routine. We hope you like it.
A little nitpicky, but its `.travis.yml` not `travis.yml`.
