> The uncompressed, compressed size of each column of an RCFile is stored in
> the header of an RCFile block. Currently, we have no convenient way to get
> at this data. This would be useful for identifying where RCFile is doing a
> poor job of compression, so that we can better focus our efforts.
> RCFileCat seems like a logical tool to extend to add this.
