Example usage "-Mode=Analyze UnrealEditor Win64 Development".
The tool currently outputs the following files:
* A graph of dependencies between modules, with edges indicating unique outward references (eg. if module A depends on Core and BuildSettings, but Core depends on BuildSettings, an edge will only be shown from A -> Core).
* A graph showing shortest path from the target to each module.
* A text file listing all modules in the target, their references to other modules, the shortest path causing them to be instantiated, and a (very) rough estimate of their size taken by measuring the sum of all object files or output files that already exist on disk.
* A csv file containing the same information as above.
Graphs are output in GEFX format, and can be viewed using Gephi.
