//    - This song is dedicated to those who lost their lives and/or loved ones in the 2023     //
//      Turkey-Syria earthquakes.                                                              //
//    - A sage once said: "Don't be in a hurry. Be sensitive. Start by creating a              //
//      collaboration for now. It is not right to try to deliver all the aid through a         //
//      single channel. Those who are truly in trouble will be identified over time. For       //
//      now, the clamorers might make themselves more prominent; those who shout the           //
//      loudest might be the ones who are less injured and more timid. Those who remain        //
//      silent, however, are both harder and later to reach."                                  //
//    - As the initial intense (and admirable, of course) interest in the disaster area        //
//      slowly began to fade, I had a feeling that the "time" the sage spoke of had            //
//      arrived, so I made "Yardimci (The Helper)" to do some small but impactful good.        //
//    - All proceeds (including resale royalties) from the NFT of this song will go            //
//      "directly" to ankarelief.org's Ethereum address for earthquake donations.              //
//    - I chose ankarelief.org based on my observations that                                   //
//      [a] it is a secure, transparent and "sustainable" crypto fund built on a               //
//          "multi-signature" basis;                                                           //
//      [b] there are competent and influential people (industry leaders) among these          //
//          multi signers; and                                                                 //

/**
 * @dev Library for reading and writing primitive types to specific storage slots.
 *
 * Storage slots are often used to avoid storage conflict when dealing with upgradeable contracts.
 * This library helps with reading and writing to such slots without the need for inline assembly.
 *
 * The functions in this library return Slot structs that contain a `value` member that can be used to read or write.
 *
 * Example usage to set ERC1967 implementation slot:
 * ```
 * contract ERC1967 {
 *     bytes32 internal constant _IMPLEMENTATION_SLOT = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;
 *
 *     function _getImplementation() internal view returns (address) {
 *         return StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value;
 *     }
 *
 *     function _setImplementation(address newImplementation) internal {
 *         require(Address.isContract(newImplementation), "ERC1967: new implementation is not a contract");
 *         StorageSlot.getAddressSlot(_IMPLEMENTATION_SLOT).value = newImplementation;
 *     }
 * }
 * ```
 *
 * _Available since v4.1 for `address`, `bool`, `bytes32`, and `uint256`._
