[Halld-offline] Data Management Plans

[Curtis A. Meyer]

Unfortunately, it is a bit more than just the four-vectors. There also needs to be a release of matching
Monte Carlo data to be able to use the data.

For example if what is show is a histogram (1D) which is the result of statistical analysis of 20GB of 4 vectors, then provide the 20GB file so others can try their own cuts on the data.  So probably not the raw data, but probably the N-tuples.  Yes, needs discussion and then specificity to satisfy the directive.
