1.  Any significant changes should be accompanied by tests. The project already
    has good test coverage, so look at some existing tests if you're unsure how
    to go about it.
2.  All contributions must be licensed Apache 2.0 and all files must have a copy
    of the boilerplate license comment (can be copied from an existing file).
3.  Files should be formatted according to Google's [Java style guide][].
