* When a snapshot is made, the balances and totalSupply at the time of the snapshot are recorded for later
* access.
*
* To make a snapshot, call the `snapshot` function, which will emit the `Snapshot` event and return a snapshot id.
* To get the total supply from a snapshot, call the function `totalSupplyAt` with the snapshot id.
* To get the balance of an account from a snapshot, call the `balanceOfAt` function with the snapshot id and the
* account address.
