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

* The preferences class provides a relatively simple way to save important
|
|
* values to
|
|
* the RoboRIO to access the next time the RoboRIO is booted.
|
|
*
|
|
* <p>This class loads and saves from a file
|
|
* inside the RoboRIO. The user can not access the file directly, but may
|
|
* modify values at specific
|
|
* fields which will then be automatically periodically saved to the file
|
|
* by the NetworkTable server.</p>
|
|
*

* <p>This class is thread safe.</p>
|
|
*
|
|
* <p>This will also interact with {@link NetworkTable} by creating a table
|
|
* called "Preferences" with all the key-value pairs.</p>
