Overview

These rules were initially forked from pubref/rules_kotlin. Key changes:

Replace the macros with three basic rules. kotlin_binary, kotlin_library and kotlin_test.
Use a single dep attribute instead of java_dep and dep.
Add support for the following standard java rules attributes:
- data
- resource_jars
- runtime_deps
- resources
- resources_strip_prefix
- exports
Persistent worker support.
Mixed-Mode compilation (compile Java and Kotlin in one pass).
