Merge pull request #2 from alperaydemir/master

This pull request is to show what I'm running
Merge branch 'master' of github.com:matt-42/cuimg
Improve the tracking sample: Lower the detector frequency and display the trajectories
Added main2.cc (my modifications of the tracking example) in order avoid conflits with upstream
Merge branch 'upstream/master'

Conflicts:
	samples/tracking/main.cc
Measure time also with gettimeofday()
Some changes to the sample in the original repository (trying to match the inpunt in 'main2.cc')
