- OO rewrite of key/addr generation interface (KeyGenerator,AddrGenerator) - New data objects: PrivKey,PubKey,WifKey - rewrite of read-only attr implementation for addr/tx/tw list entries (MMGenImmutableAttr,MMGenListItemAttr descriptors) - txsign: build key list of addrlist objects rather than addr,key tuples
