My thought was to tie this into the right() and wrong() methods so that 
it was automatic. Perhaps there should be a doing() method to track 
fine grained progress.

Yes, that would be true, but it is a small, narrow interface.

I don't know the answer to any of these questions.

I do know that batch performance is important and that it is a struggle 
to get people to add high performance interfaces to their code so that 
Fit can test against those interfaces instead of testing against the 
top. Perhaps adding a progress indicator to slow tests is to 
misunderstand the root problem.
