Yes that would be great. First see if there is an issue for it, but  
otherwise open another. Attach patches to it, etc.

I'm not familiar with IDEA as I use Eclipse. If you'd like to check in  
project settings for IDEA let me know.

I'll spend some time pointing out the classes of interest and probably  
the best order to do them in. As to the structure of a module, I'll  
add that documentation to the code files.

Many thanks!!
