性能

在4核4G的个人电脑上测试，如下：

// go test -test.bench=".*"
BenchmarkFind-4      2000000          841 ns/op

// 2016-11-19
BenchmarkFind-4   	 2000000	       783 ns/op
BenchmarkFind2-4      100000         14106 ns/op

// 将原来的循环查找，改为二分法查找
BenchmarkFind-4    	10000000	       136 ns/op
BenchmarkFind2-4   	10000000	       133 ns/op
