The way that CVS updates are incorporated into the survey tool, all entries from
CVS are deleted, then CVS is imported. Because the votes are by path, this can
cause a user's vote to switch to something that they didn't intend when the
value in CVS changes.
This was not a problem where we weren't updating CVS during data
submission/vetting, but now that we are doing continual submission in the next
Maybe needs to have votes associated with path+value?
