> 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.
