use_cmc set to False

[RotsteinNoam]

Hi and congratulations on your great work!
In the demo.py script,
The "use_cmc" flag for the UCMCTrack is set to False.
Is this on purpose? Is this the best configuration? what does this mean?

‘use_cmc' set to False means that the gmc file will not be used. For MOT17, use gmc file yields better results. For other datasets, UCMCTrack yields better results without gmc files.
