Issues with translation

uber-hyper.js

//Once you start converting 
{
  "uber": {
    "data": [
      {"name": "givenName", "value": "Will"}, 
      {"name": "givenName", "value": "Tom"}
    ]
  }
}
//to (other fields elided)
{
  "givenName": ["Will", "Tom"]
}
//you're going to have trouble with 
{
  "uber": {
    "data": [
      {"name": "givenName", "value": "Will"},
      {"name": "lastName", "value": "Williams"},
      {"name": "givenName", "value": "Tom"},
      {"name": "lastName", "value": "Thompson"}
    ]
  }
}
//because now you'll have munged it to (other fields elided)
{
  "givenName": ["Will", "Tom"], 
  "lastName": ["Williams", "Thompson"]
}
//and lost the connection between Will and Williams.
