/data/index.js is the data cleaner/importer. the result of /data/ is a data object.
/data/index.js uses altNames.js to reformat/clean some items.

/search.js imports the data object, and sets up a search function
meanwhile, /format.js sets up a prettyprint function

finally, /index.js receives user's messages, and calls /search.js. if a result is found,
pass the result to the format function.
