The current feed forward calculation is only useful for velocity PID controllers where F, the feed forward constant, is 1 over the maximum setpoint for the output. For motion profiles which use position PID controllers, the appropriate calculation for velocity and acceleration feed forwards is different. This change allows the user to provide their own feed forward implementation without having to rewrite the entire Calculate() function.
Both default feed forward calculations are velocity feed forwards. Suggestions for sensible feed forward constants are included in the inline comments.

Years update, references to WIND_BASE were removed, and WPILib license was
moved to the root directory of the project.
If there was already a comment block, a year range through 2016 was created
using the first year in the comment. If there was no comment block, a block
with just the year 2016 was added.
Comments were not added to files from external sources (NI, CTRE).

Also provide templated varags constructor for backwards compatibility and
ease of use.
Update PIDController to use new constructor, eliminating static function
CallCalculate().

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.
