屏蔽掉一些log输出
更新于20171114
a. 解决Open找不到问题，是record数组访问越界造成的，访问越界是之前的K线有问题导致的。
更新于20171113
a. 过滤掉起始时间不正确的k线组合
b. 过滤掉时间间隔不正确的k线组合
更新于20170622
a. RecordsManager 增加Name参数,便于区分不同的K线
b. Fix 当固定K线数目不满一根新K线周期时,Time计算不正确的问题
更新于20170531
a. fix Volume计算错误
1. 修改自小小梦的"转换任意K线周期" 模板
原理：
- 获得固定K线的周期，然后合成任意固定K线整数倍的新K线周期
功能：
- 转换基础K线为任意K线周期
- 暂时不支持 秒级别
限制:
- 新K线周期必须是固定K线周期的整数倍.
- 固定K线周期为1min, 3min, 5min, 15min, 30min, 新K线周期也必须是分钟且<60
- 固定K线周期为1hour, 新K线周期也必须是小时且<24
- 固定K线周期为1day, 新K线周期也必须是天
- 每次获得的固定K线周期数目必须>=2
测试版本，如有BUG ，问题 欢迎留言。

guigui17f 211行，如果把 isFirstFind 声明在函数内部的话后面else那部分可以去掉，因为每次 isFirstFind 都是true，每次进的都是第一个分支，可以打Log看一下。
xiaoxiaolu TypeError: cannot read property 'Time' of undefined at main (__FILE__:525) 基本上运行一天就出现这样的报错停止，生成的K线有时候找不到Time
中本姜 const newRecords = recordManager.AssembleRecords(records, period) 这一句用错了吧? 不应该是period 应该可以不写 (不写的话,程序会用records算K线间隔),或者写上records中K线的时间间隔毫秒数
中本姜 const newRecords = recordManager.AssembleRecords(records, period) 这一句用错了吧? 不应该是period 应该可以不写,或者写上records中K线的时间间隔毫秒数
zrcahyx 我自己确认过了，是回测开始时间太早导致的，建议可以在代码里Log一下
guigui17f 应该是为了避免重复计算？但是放外面的话如果中途有一段时间没有获取新数据，是不是会导致计算错误呢？感觉还是每次算一下的保险~~
中本姜 能给一下RecordsManager() 以及AseembleRecords() 中给的参数是什么吗，我可以debug一下。
中本姜 的确如你所说，我还是没能理解小小梦当时的逻辑，我再研究研究改改。
zrcahyx main:98:14 - TypeError: Cannot read property 'length' of null / main:242:57 TypeError: cannot read property 'Time' of undefined 同样会出现这个问题
中本姜 哦,好吧,我有时间看看code改改, 如果再出现问题了,把原K线和新K线说一下,我看看能不能重现
xiaoxiaolu 不清楚啊 代码一多 都不知道问题在哪里 但是小梦梦的原版合成模板可以正常使用
中本姜 你的固有K线和新K线设置的什么？我一直用着，跑几个月没问题啊
