Skimming REST Data Challenge Data

• I have created a factory for skimming data into different output REST files. It will be available soon.
• Below are some statistics on the data challenge data for various potential topologies/skims.
• Data challenge data-set size: ~6.5 billion events, 50k events per file: ~130k files, ~100 MB per file: 13 TB total.

• Note: For a charged particle to be valid, it must have 45.0 < Vertex-Z < 85.0.
• Note: For a pi0 to be valid, it must have 0.1 < Invariant Mass < 0.17.
