Our execution timeline is slightly different from nextflow's execution timeline.

As a part of #58, I made a script that plot's the execution timeline, similar to that generated by nextflow. There is a slight difference between our plot and nextflow's.
Whereas the bar on the most right of nextflow's execution timeline (colored dark grey in the image below) represents the termination time, ours represents staging and unstaging time. This is not a big deal, however this is an important distinction to note. I did ask for assistance in nextflow's slack, however it seems that nextflow does not provide the termination time directly.
