There are a few kinds of files generated by RExpression:
1. complex data transfer from one RExpression actor to another
2. temporary files for long script input (not complex data, just long data)
3. graphics output (whether used for reporting or not)

The first 2 are usually not needed unless you're doing some hardcore debugging.
The graphics could be saved in provenance on their own, but I think that is
redundant when reporting is enabled since the images are grabbed and put in
provenance as tokens for use in the reports.

Basically anything here could be wiped clean on initialize, and you'd only be
able to access the last one that ran (before it was blown away):
/Users/leinfelder/.kepler/cache-2.0.0/modules/r/tpc09-plant-dynamics-woody_1266009177777
