another account. The approval is cleared when the token is
transferred.
Only a single account can be approved at a time for a token_id.
To remove an approval, the approver can approve their own address,
effectively removing the previous approved address. Alternatively,
setting the live_until_ledger to 0 will also revoke the approval.

fn __constructor(

)Transfers the token with token_id from from to to by using
spenders approval.
Unlike transfer(), which is used when the token owner initiates the
transfer, transfer_from() allows an approved third party
(spender) to transfer the token on behalf of the owner. This
function verifies that spender has the necessary approval.
