Macro near_contract_standards::impl_non_fungible_token_approval

macro_rules! impl_non_fungible_token_approval {
    ($contract: ident, $token: ident) => { ... };
}

👎Deprecated: implement the near_contract_standards::non_fungible_token::NonFungibleTokenApproval trait manually instead.

Non-fungible token approval management allows for an escrow system where multiple approvals per token exist.
