// Creates one or more hbar/token approved allowances <b>relative to the owner account specified in the allowances of
// tx transaction</b>. Each allowance grants a spender the right to transfer a pre-determined amount of the owner's
// hbar/token to any other account of the spender's choice. If the owner is not specified in any allowance, the payer
// of transaction is considered to be the owner for that particular allowance.
// Setting the amount to zero in CryptoAllowance or TokenAllowance will remove the respective allowance for the spender.
//
// (So if account <tt>0.0.X</tt> pays for this transaction and owner is not specified in the allowance,
// then at consensus each spender account will have new allowances to spend hbar or tokens from <tt>0.0.X</tt>).
