 -MD5 Index
-  -do I create an index of MD5 table hashes?
-    (how do I lookup each table to compare)
-  -add index comparison feature
+  -add column, fp_count NUMBER (number of fingerprints for this md5 schema)
+  -complete populating the second index
 
 -add "-idxf" "--index_force" to force a re-index
   -first give info about current index
