-Registrar implements the Ethereum name registrar services mapping
-- arbitrary strings to ethereum addresses
-- hashes to hashes
-- hashes to arbitrary strings
-(likely will provide lookup service for all three)
-
-The Registrar is used by
-* the roundtripper transport implementation of
-url schemes to resolve domain names and services that register these names
-* contract info retrieval (NatSpec).
-
-The Registrar uses 3 contracts on the blockchain:
-* GlobalRegistrar: Name (string) -> Address (Owner)
-* HashReg : Key Hash (hash of domain name or contract code) -> Content Hash
-* UrlHint : Content Hash -> Url Hint
-
-These contracts are (currently) not included in the genesis block.
-Each Set<X> needs to be called once on each blockchain/network once.
-
-Contract addresses need to be set the first time any Registrar method is called
-in a client session.
-This is done for frontier by default, otherwise the caller needs to make sure
-the relevant environment initialised the desired contracts
