entries

[bengreenier]

as we enter values into keys in the res object, here's what we do:

if the value has no key (we could call node app.js value value2) the entries go in _root: at the root level of res.

if the key property of res is already set to...

• an array, we simply push the new value to that array
• an object, we create _root: as per issue 8
• anything else, we make the key an array, and store both values in it (old value first)
