Interface for viewing method byte code

[masterav10]

codecache4j should provide a user interface to view byte code counts for methods.

Method measurements will need to be done at runtime to account for runtime instrumentation.

The current plan is to provide a GUI interface that can be used to identify methods in a class, and show their current implementation in the same way javap works. Runtime instrumentation will be provided through a Java Agent (as described in the java.lang.instrument package specification).
