Sign transaction

let tx={target:'DD7e7e1b322d0649000976b469561ed8a44501ce5094662e1befa61f061b991752',value:new BigNumber('10000000000'),gas:3000,gasPrice:500,nonce:15,type:0};
let h=signer.genTxHash(tx);
let s=signer.sign(h, '0xf241759f4e85b2188314c4636e88b8b8076606b53ebe9817bbe1b2379b930ca6');
tx.sign=s;

Sign recover

let sd = signer.hexToSign(s)
signer.recoverAddress(signer.genTxHash(tx),sd) ,'want',signer.getAddressFromPrivateKey('0xf5e4c655df9b6618781d4a04b645209c2e468391d72b145ff0d2f3fee155e399')

Serialize Transaction

let stx = signer.serializeTX(tx);
//deserialization just utilize JSON.parse
let txObj = JSON.parse(stx);
