 /**
  * Formats the messages returned by Respect Validator's NestedValidationException
  *
  * Instead of returning all the messages as a simple array it maps the message to the name of the input field so
  * that way it is easier to parse the messages when they're sent back to the front end.
  *
  * Heavily inspired by NestedValidationException->getAllMessages()
  * @todo make sure $input isn't null
  * @todo handle collision in keys
  * @param NestedValidationException $exceptions
  * @return array
