ITokenBundle

Group together arbitrary ERC20, ERC721 and ERC1155 tokens into a single bundle. The Token struct is a generic type that can describe any ERC20, ERC721 or ERC1155 token. The Bundle struct is a data structure to track a group/bundle of multiple assets i.e. ERC20, ERC721 and ERC1155 tokens, each described as a Token. Expressing tokens as the Token type, and grouping them as a Bundle allows for writing generic logic to handle any ERC20, ERC721 or ERC1155 tokens.
