if the concurrent value was greater than the total chromosomes we end up with
a divide by zero error when calculating the chunk size.
if a chromosome has zero expected files don't display the results as
they are just confusing and useless.
do not hide the zerod targets if --detail is specified and clean up the max_procs a bit to make it more readable
* fix divide by zero bug when concurrent is specified but is greater than the total chromosomes.
* hide the steps/chromosomes with zero expected files unless --detail is specified
