Add function changeFieldName

[cwgroppe]

Would it be possible to add a function called changeFieldName or updateFieldName?

It would probably look something like this:

def changeFieldName(from: String, to: String): Unit = {
 val fromVal = underlying.selectDynamic(from)
  fromVal match {
    case null => ()
    case     _ => {
      underlying.remove(fromVal)
      underlying += ((to,fromVal)) 
    }
  }
}

Does this go against what you're trying to build here? If not, I will add it. Would there be anything else that would be needed?
