The decorator/simple_log.go file

Our logger leverages Go's Logger package, as follows:

package decorator

import (
       "io"
       "log"
       "os"
)

var (
       Debug   *log.Logger
       Info    *log.Logger
       Error   *log.Logger
       InfoHandler io.Writer
)

A simple logger exports one function, namely InitLog, which the calling package uses to enable the logging features:

func InitLog(
       traceFileName string,
       debugHandler io.Writer,
       infoHandler io.Writer,
       errorHandler io.Writer,
) {
