ovrHmd_StartPerfLog - added in SDK 0.4.3

So JeffBail brought a couple of new functions in 0.4.3 to my attention:

OVR_EXPORT ovrBool ovrHmd_StartPerfLog(ovrHmd hmd, const char* fileName, const char* userData1);
OVR_EXPORT ovrBool ovrHmd_StopPerfLog(ovrHmd hmd);

Did everybody know about this? Just turn it on and it dumps a 17 column row to a .csv file in C:\Users\YourUsername\AppData\Local\Oculus\ once per second.

    One thing I noticed is that it doesn't seem like you can create log files in other directories. I tried using "C:\\temp\\logfile.csv" and it didn't seem to work. This is a really nice feature & it deserves mention in the developer's guide.

    Has anyone found a way to monitor the output while a (windows) application is running? It seems the file is locked and doing "Get-Content -wait" from PowerShell and "tail -f" from cygwin don't work. I tried some other tail & log viewer applications but none of them seemed to update until the application was closed.
