* Manages and stores AuthSub tokens.

* in-memory. This is just for the purposes of the sample. Ideally, the
* token should be stored in a database with the same security restrictions
* as other sensitive material like user passwords. Google limits the
* number of AuthSub tokens generated per user per target and thus the tokens
* have to be stored permanently and reused.
