Result Reporter Tool

Goal of this project is to use coala's json output format, convert it to various test result formats and then integrate these test format reports to various tools like CricleCI, Appveyor, Jenkins and Phabricator. Result format inconsistencies has been a problem for a long time but the benefit of converting the static analysis results into a test result format can provide tight integration with various systems. This project also aims to provide our upstream linters with some of these test formats using the Result Reporter Tool library and help developers in extending this project to other formats and uses in the future.
