Implement method do get all existing key-value pairs in a store

[philippgille]

As mentioned in the README already, something like List(interface{}) error or GetAll(interface{}) error should be implemented.

Example of how a user could pass a slice which the List method then populates with values:

package main

import (
	"encoding/json"
	"fmt"
)

type foo struct {
	Bar string
}

// myFunc is meant to populate the passed slice of pointers
func myFunc(vals interface{}) {
	j := []byte(`[{"Bar":"baz1"},{"Bar":"baz2"}]`)

	err := json.Unmarshal(j, vals)
	if err != nil {
		panic(err)
	}
}

func main() {
	fmt.Println("Hello world!")

	vals := make([]foo, 0)
	myFunc(&vals)
	fmt.Println("vals:")
	for _, v := range vals {
		fmt.Printf("%+v\n", v)
	}
}

Output:

Hello world!
vals:
{Bar:baz1}
{Bar:baz2}
