Fix B/W reporting for raw vs weighted I/O rates.

[maherou]

Current B/W report does not correctly the raw B/W values. Here is the correct code:

doc.add("GB/s Summary","");
doc.get("GB/s Summary")->add("Raw Read B/W",fnreads/times[0]/1.0E9);
doc.get("GB/s Summary")->add("Raw Write B/W",fnwrites/times[0]/1.0E9);
doc.get("GB/s Summary")->add("Raw Total B/W",(fnreads+fnwrites)/(times[0])/1.0E9);
doc.get("GB/s Summary")->add("Total with convergence and optimization phase overhead",(frefnreads+frefnwrites)/(times[0]+fNumberOfCgSets*(times[7]/10.0+times[9]/10.0))/1.0E9);

Completed.
