[Ipopt] Getting Accurate CPU Times from Ipopt

[Stefan Vigerske]

Ipopt uses some standard functions (getrusage()) to measure CPU time, 
see IpUtils.cpp. I don't think that there is a more accurate measurement 
of time than that. I don't know the mex interface, but unless it does 
not just pass on the time measurement from Ipopt, there is little one 
could improve, I believe.

I am using the MATLAB mex files compiled by Enrico Bertolazzi for my runs.  I am finding that Ipopt does not seem to provide accurate CPU times using the CPU time output from the mex interface.  I am grateful if somebody might be able to help me get an accurate execution time.  Thanks for your help.
