// Program to Test Hash Table Class

// Program is driven by command input:
//   i url -- insert "url" into hash table; report whether it's
//              already there.
//   q url -- query table for "url"; report success/failure.
//   r url -- remove "url" from table; report whether it was there.
//   p     -- print contents of table.
//   end-of-file to quit
// Lines beginning "#" are ignored.
