 * <ul>TransferValidation: Implements the basic token transfer validation interface.</ul>
 * <ul>ICreatorToken: Implements the interface for creator tokens, providing view functions for token security policies.</ul>
 *
 * <h4>Benefits:</h4>
 * <ul>Provides a flexible and modular way to implement custom token transfer restrictions and security policies.</ul>
 * <ul>Allows creators to enforce policies such as whitelisted operators and permitted contract receivers.</ul>
 * <ul>Can be easily integrated into other token contracts as a base contract.</ul>
 *
 * <h4>Intended Usage:</h4>
 * <ul>Use as a base contract for creator token implementations that require advanced transfer restrictions and
