线上环境有时候也需要启用vconsole来调试程序，来回部署又有些不方便
想了一个好玩的办法来隐藏vconsole
想要设置一个debug开关，在开启之后呢，我就一直处于debug模式可以使用vconsole
保持状态可以使用localstorage
开关我用的是触摸事件输入摩尔斯码开启的
大改是这个逻辑
1.设置个存放正确密码在success数组，和存放输入密码的action数组
2.监听触摸的时间长短来判断是tap还是press
3.输入的这位对应success对应位置的密码正确，就放进action数组，错误就清空action数组
4.当success数组等于action数组时，就开启开关啦

(function () {

    var _YK_VC_OPEN_ = '_YK_VC_OPEN_'

    var shouldOpen = localStorage.getItem(_YK_VC_OPEN_) === _YK_VC_OPEN_

    if (shouldOpen) {
        open()
    } else {
        lock()
    }

    function open() {
        var vConsole = new VConsole();
    }

    function lock() {
        /*
