8/// Backpointer
9///
10/// Since the backpointer account address is derived from the wrapped mint, it
11/// allows clients to easily work with wrapped tokens.
12///
13/// Try to fetch the account at `get_wrapped_mint_backpointer_address`.
14///  * if it doesn't exist, then the token is not wrapped
15///  * if it exists, read the data in the account as the unwrapped mint address
16///
17/// With this info, clients can easily unwrap tokens, even if they don't know
18/// the origin.
