A command line tool to find java leaf reference.

In a big java project, after change some code, it is good to have a tool to find the impacted methods. The leaf reference maybe unit test cases, public methods. It would be good that developer can prioritize to test those impacted leaf reference.

Of cause developer can use find reference in IDE or experience to figure out the scope to test the change, but CI have no idea about the change. In case there are many unit test cases and function test cases need to be run in CI before merge the code, it's wast to run all of them when developer only change a little bit.

The ambition of this tool is to help developer find the leaf reference and provide extra information to CI or other tools.
