postscript file with histograms of some federation attributes

[David Zimmerman <zimm@physgi01f.phy.bnl.gov>]

Hi,
The attached postscript file contains three histograms

101 	The number of events in each data base
102 	The file size (from ls) of each data base file
103	The ratio of the file size to number of events for each data base

Since the FileID for the cluster header is a queryable quantity it
is possible to insist that selected events come from specific
databases.
