1. Make sure that "dot" can be found in the path

Browse Source 
2. Fix a bug where the lib directory specified also had to be cwd
3. Weight the output so archive->archive edges are shorter
4. Generate two different graphs: one for libraries, one for objects.
5. Adjust the properties of the graphs till it looks nice.
