Golang Job Queue

A running example of the code from:

• http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang
• http://nesv.github.io/golang/2014/02/25/worker-queues-in-go.html

Step 1

Small refactorings made to original code:

package main

import (
	"fmt"
	"reflect"
)

//function types
type mapf func(interface{}) interface{}
