	Balance  *big.Int
	Root     common.Hash // merkle root of the storage trie
	CodeHash []byte
	Res      Resource  // resource for account
	Stakings []Staking // slice of regular mortgaging

func (*StateDB) CreateAccount 

func (self *StateDB) CreateAccount(addr common.Address)

CreateAccount explicitly creates a state object. If a state object with the address already exists the balance is carried over to the new account.

CreateAccount is called during the EVM CREATE operation. The situation might arise that a contract does the following:

  1. sends funds to sha(account ++ (nonce + 1))
  2. tx_create(sha(account ++ nonce)) (note that this gets the address of 1)

Carrying over the balance ensures that Inber doesn't disappear.
