A TransactionBuilder is a transaction class that's mutable (unlike the others which are all immutable). It is intended to be passed around contracts that may edit it by adding new states/commands. Then once the states and commands are right, this class can be used as a holding bucket to gather signatures from multiple parties.
The builder can be customised for specific transaction types, e.g. where additional processing is needed before adding a state/command.
notary - Notary used for the transaction. If null, this indicates the transaction DOES NOT have a notary.
When this is set to a non-null value, an output state can be added by just passing in a ContractState – a
TransactionState with this notary specified will be generated automatically.
