写了一个简单的log库

参照大牛的代码，写了一个简单的log 库，使用起来还是蛮简单的。 ``` package main import ( "fmt" . "github.com/flike/golog" "os" ) func main() { path := "/tmp/test_log" os.RemoveAll(path) os.Mkdir(path, 0777) fileName := path + "/test.log" h, err := NewRotatingFileHandler(fileName, 1024*1024, 2) if err != nil { fmt.Println(err.Error()) } //GlobalLogger is a global variable GlobalLogger = New(h, Lfile|Ltime|Llevel) GlobalLogger.SetLevel(LevelTrace) args1 := "go" args2 := "log" args3 := "golog" //the log will record into the file(/tmp/test_log/test.log) Debug("Mode", "main", "OK", 0, "args1", args1, "args2", args2, "args3", args3) GlobalLogger.Close() } ``` https://github.com/flike/golog
