/**
* Create a new token. After the token is created, the Token ID for it is in the receipt.
* The specified Treasury Account is receiving the initial supply of tokens as-well as the tokens
* from the Token Mint operation once executed. The balance of the treasury account is decreased
* when the Token Burn operation is executed.
*
* The initialSupply is the initial supply of the smallest parts of a token (like a
* tinybar, not an hbar). These are the smallest units of the token which may be transferred.
*
* The supply can change over time. If the total supply at some moment is S parts of tokens,
* and the token is using D decimals, then S must be less than or equal to
* 263-1, which is 9,223,372,036,854,775,807. The number of whole tokens (not parts) will
* be S / 10D.
*
* If decimals is 8 or 11, then the number of whole tokens can be at most a few billions or
* millions, respectively. For example, it could match Bitcoin (21 million whole tokens with 8
* decimals) or hbars (50 billion whole tokens with 8 decimals). It could even match Bitcoin with
* milli-satoshis (21 million whole tokens with 11 decimals).
*
* Note that a created token is immutable if the adminKey is omitted. No property of
* an immutable token can ever change, with the sole exception of its expiry. Anyone can pay to
* extend the expiry time of an immutable token.
*
* A token can be either FUNGIBLE_COMMON or NON_FUNGIBLE_UNIQUE, based on its
* TokenType. If it has been omitted, FUNGIBLE_COMMON type is used.
*
* A token can have either INFINITE or FINITE supply type, based on its
* TokenType. If it has been omitted, INFINITE type is used.
*
* If a FUNGIBLE TokenType is used, initialSupply should explicitly be set to a
* non-negative. If not, the transaction will resolve to INVALID_TOKEN_INITIAL_SUPPLY.
*
* If a NON_FUNGIBLE_UNIQUE TokenType is used, initialSupply should explicitly be set
* to 0. If not, the transaction will resolve to INVALID_TOKEN_INITIAL_SUPPLY.
*
* If an INFINITE TokenSupplyType is used, maxSupply should explicitly be set to 0. If
* it is not 0, the transaction will resolve to INVALID_TOKEN_MAX_SUPPLY.
*
* If a FINITE TokenSupplyType is used, maxSupply should be explicitly set to a
* non-negative value. If it is not, the transaction will resolve to INVALID_TOKEN_MAX_SUPPLY.
