ENH: Display module name in qSlicerCLIProgressBar
Created by: agirault
This commit allows to display the name of the CLI module node in the top left corner of the progressbar. This new feature follows the same implementation than for the status visibility and the progressbar visibility. By default the CLI module node name is always hidden.
Rational :
When creating a python module running a pipeline of CLI modules, we usually link our main progressbar to the current CLI node. This practice helps following the progress of one module, but was lacking information regarding our progress in the whole pipeline. Displaying the name of the CLI module node above the progressbar allows for more explicit information.
