ORBIT-USER: OML Logging

[chris at orderonenetworks.com]

It turns out my problem was that I assumed a crash occured because the
correct parameters were not be passed through the command line to
initialize_oml. It turns out the real issue was an extra '&'.

If you look at page
http://www.orbit-lab.org/wiki/Tutorial/CollectMeasurements under
'Application Code Sample', you see the line:

initialize_oml(&argc, &argv, NULL);

it should be (at least the way it solved it for me)

initialize_oml(&argc, argv, NULL);

I spent _hours_ assuming the crash was because the --oml* parameters were
not being passed when I typed in the command line myself to check my code,
but when the nodehandler called my app, it would pass those and all would
be fine. When I logged my command line to disk, the nodehandler never sent
them, so I spent ages trying to figure out why not. Turns out I was
chasing the wrong thing..

Thanks everyone for the help.
Chris
