 The issuer must provide metadata object of the Issuer. Optionally, Issuer can also provide metadata object for each token class.
 Issuer level (contract) metadata, must provide information common to all tokens and all classes defined by the issuer. Class level metadata, must provide information common to all tokens of a given class. Information should be deduplicated and denormalized whenever possible.
-Example: if all tokens of a give class share the same symbol and icon, then both icon and symbol must be defined in the `ClassMetadata` and left empty (`None`) in the token metadata level. If a particular SBT (token) has to have unique icon, but we would like to keep a default icon for all tokens of a given issuer, then we can have default icon defined in the `ContractMetadata.icon` and each SBT, that has to have different icon, can have it specified in `TokenMetadata.icon`.
