This is a wallet in the sense that it conforms to the interface needed by WalletStateManager.
It is not a user-facing wallet. A user cannot spend or receive XCH though a wallet of this type.
Wallets of type CAT and DAO_CAT are the user-facing wallets which hold the voting tokens a user
owns. The DAO Wallet is used for state-tracking of the Treasury Singleton and its associated
Proposals.
State change Spends (spends this user creates, either from DAOWallet or DAOCATWallet:
* Create a proposal
* Add more votes to a proposal
* Lock / Unlock voting tokens
* Collect finished state of a Proposal - spend to read the oracle result and Get our CAT coins back
* Anyone can send money to the Treasury, whether in possession of a voting CAT or not
Incoming spends we listen for:
* Update Treasury state if treasury is spent
* Hear about a finished proposal
* Hear about a new proposal -- check interest threshold (how many votes)
* Get Updated Proposal Data
