As proposed in http://openjdk.java.net/jeps/162, add a tool to analyze class dependencies to help developers prepare for the modular platform.

Provide a command-line tool in the JDK so that developers can understand the static dependencies of their applications and libraries — As part of Project Jigsaw, a useful class analyzer was developed that makes it very easy to identify the dependencies. This class analyzer will be modified to make it easy to identify the usage of non-standard and JDK internal APIs and would provide a useful complement to the warnings emitted by javac when compiling code that make use of JDK internal APIs.
