Consider providing CFG as a part of output

As of now, CFG is displayed in GUI. 
It would be of great help if that graph is outputted along with other output files. A lot of papers talk about malware detection using CFG analysis, so providing CFG (which you are generating anyway) is much helpful. 
Along with disasm, functions and import files, you can output cfg file which has cfg in form of adjacency matrix or adjacency list.
