> To improve the understability of the pipeline planning stages it would help to visualize
some intermediate planning states like:
> - PCollection lineage. (visualizing the output-pcollection-targets structure) 
> - MSCRPlanner's planning Graphs before and after the split up of dependent GBK nodes
> - RTNode hierarchy along with the Input and Output configurations as persistent in the
Configuration before the execution of the pipeline. 
> Most of the information can be intercepted in the MSCRPlanner#plan()  method.
