    15 /* This class supports case insensitive lookup.

    16  *

    17  * It differs from atom tables:

    18  * - It supports case insensitive lookup.

    19  * - It has minimal footprint by not copying the string table.

    20  * - It does no locking.

    21  * - It returns zero based indexes and const nsCString& as required by its

    22  *   callers in the parser.

    23  * - It is not an xpcom interface - meant for fast lookup in static tables.

    24  *

    25  * ***REQUIREMENTS***

    26  * - It *requires* that all entries in the table be lowercase only.

    27  * - It *requires* that the table of strings be in memory that lives at least

    28  *    as long as this table object - typically a static string array.
