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.

Local shader compiler:
- Not making 1 job batches (for High prio jobs) on startup
- Randomizing pending job selection to reduce chance that multiple 60+ sec jobs get into a single batch
(the above have the most effect on speed up, below is optional/misc)
- Pushing the completed jobs back to manager before, and not after, pulling new ones to reduce idle time
- Processing jobs in FIFO rather than LIFO order (change to LIFO seems like an ODSC regression? Hard to say definitively if it's a regression from the numbers, but seems odd to have the earliest jobs processed last)
- Parallel processing of input and output files (starts sequential by default to reduce the CPU overhead, but is enabled if we ever see too long write/read)
- More insights scopes
Distributed:
- Not avoiding local machine for XGE on startup
Both:
- Input file compression (disabled by default, need to better figure out when it's beneficial in a general case. Mostly for people with really slow I/O and XGE over VPN).
- More stats, also more dense stat output. Removed an unimportant one, added stats about the batches.
