Package hexutil implements hex encoding with 0x prefix.
This encoding is used by the Ethereum RPC API to transport binary data in JSON payloads.
Encoding Rules
All hex data must have prefix "0x".
For byte slices, the hex data must be of even length. An empty byte slice
encodes as "0x".
Integers are encoded using the least amount of digits (no leading zero digits). Their
encoding may be of uneven length. The number zero encodes as "0x0".

/*
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
