add keys and multiple results

1. need to add more details to a person. name alone is not enough
right now i am storing the key to the person in my db, as the name in yours. just so i could store some extra basic info.
this is not efficient.
please allow a key-value data.
2. when i try to detect a face, it only returns one, not all the matching faces with a threshold. sometimes people are similar to eachother, and the one that got the highest score, is not the right one.
