le API design

A consumer needs to lookup a single user by their github name (jordanbyron). That consumer doesn't know the user's ID. There is a possibility to also search by email and twitter.

"/users.json?github=jordanbyron"
=> [{github: "jordanbyron", id: 1}]

When there are no results an empty array is returned

"/users.json?github=noexist"
