To explain the background - the design was done based on specific 
requirements by a customer. The code was written from scratch to 
properly implement the entire logic of fixing errors and tracking the 
effect of fixing one error on other errors. But from a programming point 
of view the implementation is actually very modular and easily 
extensible. The UI is differently organized, it was felt that it allowed 
the user to more quickly set up the "check session". But as far as I'm 
concerned in it's current form I don't see it as deprecating the current 
topology checker.
