Since the Park optimiser is to be replaced by Bumps, does this error need to be fixed?

OOps .. should have added the comment when changing title from "PARK does not compute …" to the current title. Since we are removing PARK the ticket made no sense. However Paul suggests we double check that BUMPS is doing it correctly before closing this ticket. So have renamed.

Too much has changed for this ticket to still be possible to deal with. If we see any issues in future, raise new ticket.
