Docs
readOsuDB(path, callback) calls back with a string player and an array of beatmap objects called beatmaps.
readCollectionDB(path, callback) calls back with an object where the key is the collection name and the value is an array of beatmap md5 hashes.
writeCollectionDB(path, collections, callback) writes a collection database file. The collections object should be in the same format as in readCollectionDB. Be careful.
readScoresDB(path, callback) calls back with an object where keys are beatmap md5s and the value is an array containing scores objects.
