 * This class demonstrates the usage of EnumStringConverter, which is a specialized StringConverter implementation
 * for Enum types. It provides a default mechanism to format Enum values in title case, replaces underscores with spaces,
 * and capitalizes the first letter of each word. If the Enum value is null, it returns an empty string.
