/// @title AFT.sol
/// @author Fernando Viktor Seidl E-mail: viktorseidl@gmail.com
/// @notice ERC20 Token Standard Contract with special extensions in the "_transfer" functionality for the Governance *** AFT ERC20 TOKEN ***
/// @dev This ERC20 contract includes all functionalities of an ERC20 standard. The only difference to the standard are the built-in
/// extensions in the _transfer function.
/// TOKEN DETAILS:
/// - Inicial total supply 0 AFT
/// - Final total supply 1,000,000 AFT
/// - Token Decimals 0
/// - Token uniqueness _NumOnToken
/// - Token Name: Arthena
/// - Token Symbol: AFT
///
/// TOKEN USE CASE:
/// - The principal application of the AFT token is the creation of value and Governance.
/// - The token can be viewed as an auto-generating yield token with a Governance voting implementation, the AFT receives a share
/// of the overall projects income and has a 60% voting power on Governance.
