/**
 * @title   Collection fragment
 * @author  RacerDev
 * @notice  This contract is the base for a novel extension to the ERC721 standard that allows a
 *          collection to be partitioned, or fragmented, into smaller fragments.  Each fragment is allocated
 *          its own supply and defines the range of token IDs that it contains. In addition, each
 *          fragment has its own unique metadata storage URI that points to an IFPS collection containing
 *          the collection's metadata files.
 * @notice  The extension was created to allow for NFT collections to be extended, or released in phases,
 *          as opposed to having all tokens minted druing a single event.  It provides flexibility to add different/additional
 *          assets that are part of the same collection, but do not share an metadata origin with the other fragments.
 * @dev     Fragments can have an external renderer contract attached to return a `tokenURI` containing purely on-chain data
 * @dev     A Fragment is capable of issuing randomized token IDs at mint time, with the aid of seed provided by the caller. Verifying
 *          the validity of the seed is left up to the caller (usually another contract).
