A kind of status bar to see where the Search is in csp

[Torsten Anders]

Dear Luis,

I really like this approximation you propose. Of course, the 'progress  
bar' may quick go to, say, 90% and then stay there forever and  
eventually fall back again. Still, that's at least some feedback..

Best,
Torsten
