There should be a debug flag to log all Javac compiler output

[adamvoss]

Adding an option that can cause all of the output generated by Javac could make users better able to figure out what is happening when they face issues such as #37 and #20 and increase their confidence in depending on this code.

While fixing such parsing issues is good, there is nothing to prove the parsing is perfect or nothing to prevent the output from changing and breaking the parsing in the future, just this option would continue to be useful.
