Registers are a mutable piece of data on the Network.
They can be read by anyone and updated only by the register owner.
Each entry is signed by the owner and all value history is kept on the Network.
They can be accessed on the Network using the RegisterAddress which is effectively the hash of the owner’s crate::PublicKey.
This means there can only be one Register per key.
