/**
 * @author The Wukong Project Team
 * @title Wukoin - The erc20 token part of the Wukong Project that starts the crypto revolution
 * 
 * Born to be part of a big project,
 * the Wukoin Token gives holders access to a multitude
 * of present and future services of the Wukong Project's ecosystem.
 *
 * Apart from its utilities, the token comes also with some incredible tokenomics features
 * built right in the source code of its smart contract.
 * To help others, the project and yourself at the same time.
 *
 * **Share**
 * Part of the fees collected by the contract is used for charity initiatives
 * in a collective effort to make the world a better place and bring happiness
 * to its inhabitants.
 *
 * **Expand**
 * Another share of the fees goes to the marketing wallet to fund marketing campaigns,
 * with the purpose of raising people's awareness of the project.
 *
 * **Hold**
 * Even eligible holders benefit from the fees collected in the form of ETH reflections
 * and can claim them on the platform without the need to sell their own tokens: wukoin.wukongproject.com
 *
 * **Community**
 * It's all about YOU, from the beginning. The Wukoin Community fuels, funds and sustain
 * the development, expansion and charitable initiatives of the project by trading, using,
 * sharing Wukoin Tokens, discussing, helping each other and planning initiatives
 * of many kinds.
 *
 * Anti-bot
 * Our contract makes use of a powerful anti-bot system to promote a fair environment.
 * If you use bots/contracts to trade on Wukoin you are hereby declaring your investment in the project a DONATION.
