* This contract is intended to be used as a base for creator-specific token contracts, enabling customizable transfer

* <h4>Features:</h4>
* <ul>Ownable: This contract can have an owner who can set and update the transfer validator.</ul>
* <ul>TransferValidation: Implements the basic token transfer validation interface.</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 account and codehash blacklists, whitelists, and graylists.</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
* security policies.</ul>
* <ul>Set and update the ICreatorTokenTransferValidator implementation contract to enforce desired policies for the
* creator token.</ul>
*
* <h4>Compatibility:</h4>
