creating data directory for json files to go in.
updating docs
fixed bug in links.py that caused links.json to have incorrect formatting.
moved data.json to raw_data.json; wrote prepare.py to combine raw_data.json and links.json into data.json
made build.sh run data/prepare.py first; made prepare.py support running with a different working directory; also added comments to both files.  Updated data.json should reflect new links data.
