 * @dev Implementation of the NFT Royalty Standard, a standardized way to retrieve royalty payment information.

 * Royalty information can be specified globally for all token ids via {_setDefaultRoyalty}, and/or individually for

 *
 * Royalty is specified as a fraction of sale price. {_feeDenominator} is overridable but defaults to 10000, meaning the
