-// TABLE
-//
 // This module contains a library of lua functions
-// for manipulating tables.  Some of the functions only
-// work on vectors (ie, tables with integer keys starting

-// QUEUE
-//
-// This module contains a library of lua functions for
-// manipulating queues.  Queues are represented as a table
-// with a "head" and a "tail", and with integer-keyed values.
-// For example:
-//
-//      {
-//        "tail": 100,
-//        "head": 103,
-//        100: "a",
-//        101: "b",
-//        102: "c"
-//      }
-//
-// Values are pushed onto the head, and values are popped
-// from the tail.
+// for manipulating tables.  It also provides a library
+// of useful classes based on tables.
