+/* This class supports case insensitive lookup.
+ *
+ * It differs from atom tables:
+ * - It supports case insensitive lookup.
+ * - It has minimal footprint by not copying the string table.
+ * - It does no locking.
+ * - It returns zero based indexes and const nsCString& as required by its
+ *   callers in the parser.
+ * - It is not an xpcom interface - meant for fast lookup in static tables.
+ *
+ * ***REQUIREMENTS***
+ * - It *requires* that all entries in the table be lowercase only.
+ * - It *requires* that the table of strings be in memory that lives at least
+ *    as long as this table object - typically a static string array.
