OrderMap

map with ordered keys (string key only)

Usage

    m := ordermap.New()
    m.Set("n", 100)
    m.Set("f", 99.99)
    m.Set("d", "barfoo")
    m.Set("c", "foobar")
    m.Set("b", "bar")
    m.Set("a", "foo")

	// use Keys() to iterate all ordered keys
    for _, key := range m.Keys() {
        fmt.Println(key, m.Get(key))
    }
    json.NewEncoder(os.Stdout).Encode(m)

    m.Del("c")
    for _, key := range m.Keys() {
        fmt.Println(key, m.Get(key))
    }
    json.NewEncoder(os.Stdout).Encode(m)
