1. Removed SOPs from the visualization codebase. Switched it with log.debugs.

2. Added person grant count & coauthorship to the freemarker version of dependency inhection bean.
3. Fixed a bug in garnt count freemarker.
4. Made use of urlbuilder instead of making urls by just encoding/appending parameters.
5. Add co-pi to the freemarker package. Completed the back-end conversion.
