Clean up codebase before 1.3.0 release
We just ran out of tickets to be merged into 1.3.0, and I'd like to take this opportunity to make some general changes to the codebase before releasing. Things like:
- moving all Java sources to
- adding a checkstyle task and fixing most of the style issues found by checkstyle, and
- updating the copyright notice to 2016.
(I already started working on these things and will post a branch in a minute.)
What other bulk updates should we make before the 1.3.0 release?
