query selection

[dave zimmerman <zimm@rncsv1.lbl.gov>]

I have placed a set of queries to be used with the phenix data base
in the directory 
/grandch/u/GCA/bin/query/oldquery
the file is called four.query

Also there are 4 files which contain the file id's and event counts
for each of the 6 queries in the selection.

For 4 queries which overlap I recommend

query 1 which is a selective query over half the federation 

query 5 which is a less selective query over the full federation

query 3 which is a not very selective query but it runs over only
	a third of the federation.

query 6 which is a coarse selection over the full federation.
