This is a major restructuring of the WPILib repository to simply build procedures and remove the remnants of Maven from everything except the eclipse plugins. Gradle files have been largely simplified or rewritten, taking advantage of splitting up parts of the build into separate build files for ease of reading. The eclipse plugins are now in a separate project, as is ntcore. All dependencies are resolved via Maven dependencies, with the Jenkins-maintained WPILib repo. Project structures have also been simplified: we no longer have separate subprojects inside wpilibc and wpilibj. Where possible, these changes hav been done with git renames, to make sure we still have full history for all repositories. Other unrelated subprojects have also been broken out: OutlineViewer is now a separate project. Change-Id: Ib4e2a6e1a2f66427a14f16612b0e0d69ed661878

|
