/**
 * Simple utility class that creates a map for string-based keys.
 * 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 <tt>String</tt> using the
 * <tt>toString()</tt> method, since it is only intended to
 * compare strings.
