/**
 * Simple utility class that creates a map for string-based keys by
 * extending TreeMap. This map can be set to use case-sensitive
 * or case-insensitive comparison when searching for the key.
 * Any keys put into this map will be converted to
 * a String using the toString() method,
 * since it is only intended to compare strings.
