[bug]After upgrading to 0.5.1, NVM is exported by default, but native.js is imported by default in NVM, which causes the standard Date and Math objects to be replaced, and reports that 'Blockchain.block' is not defined.

升级到 0.5.1 后，默认导出了 NVM。index.js 第 8 行

var NVM = require('./lib/nvm/nvm');

但是 NVM 里面默认引入了 native.js 。nvm.js 第 4 行

var native = require("./native");

native.js 会导致在浏览器环境下标准 Date 和 Math 对象被替换

而且会报 'Blockchain.block' is not defined.(因为Date对象依赖 Blockchain.block，而浏览器环境没有这个)

建议默认不要导出 NVM
