  LIBRARY: admin.cache.php - administration of cache management tables using MW UI
  HISTORY:
    2010-11-08 extracting from SpecialVbzAdmin
    2010-11-09 renaming "data" to "cache"
	Also renamed everything "Proc" to "Query", but then later decided this was not
	  as great an idea as I originally thought because procs are really the way to do this.
    2010-11-11 renaming "query" back to "proc"
