适用于最新的 EOS Dawn 4.0/4.1
前言
最近在研究 EOS 的 RPC API，但是由于官方API文档的不够详尽，新建账号（new account）这一个操作就折腾了一个多星期。皇天不负有心人，终于调通了新建账号，代币转账也轻松解决。特地写这篇文章（适用于 EOS dawn 4.0 和 4.1），帮助准备使用 EOS RPC 做 Dapp 开发的朋友，如有问题，欢迎批评指正。

}(代币转账 和 新建账号的 sign_transaction、push_transaction 类似，主要就是 智能合约的不同 和 调用的action 的不同 以及 action 中具体的参数不同。)
新建账号（newaccount）需要用 「已有的账号」 创建「 新账号」
内部是 已有账号 调用系统智能合约eosio中的 newaccount 的 action
新建账号的交易需要用 创建者 的 私钥签名交易（sign_transaction），然后 推送签名后的交易 (push_transaction)到区块链中。
