Allow for Feature Branches instead of Single Branches to allow for easier code management.

To improve our velocity and quality of deployments we would prefer Optimizely allow us to implement changes using feature branches instead of requiring us to either bundle all changes into a single branch or work them one at a time in series. This would enable developers to create separate branches for different features, allowing for parallel development and easier code management; essentially mirroring the standard Git branching workflow where you can create feature branches for individual functionalities.
