A simple framework for implementing a Google IoT device.

This package makes use of the [context package] to handle request cancelation, timeouts, and deadlines.

Here is an example showing how to use this library:

```go

package main

import (

	"context"

	"log"

	"github.com/vaelen/iot"

	// Your client must include the paho package

	// to use the default Eclipse Paho MQTT client.

	_ "github.com/vaelen/iot/paho"

)

func main() {

	ctx := context.Background()

	id := &iot.ID{

		DeviceID:  "deviceName",

		Registry:  "my-registry",

		Location:  "asia-east1",

		ProjectID: "my-project",

	}

	credentials, err := iot.LoadRSACredentials("rsa_cert.pem", "rsa_private.pem")

	if err != nil {

		panic("Couldn't load credentials")

	}

	options := iot.DefaultOptions(id, credentials)

	options.DebugLogger = log.Println

	options.InfoLogger = log.Println

	options.ErrorLogger = log.Println

	options.ConfigHandler = func(thing iot.Thing, config []byte) {

		// Do something here to process the updated config and create an updated state string

		state := []byte("ok")

		thing.PublishState(ctx, state)

	}

	thing := iot.New(options)

	err = thing.Connect(ctx, "ssl://mqtt.googleapis.com:443")

	if err != nil {

		panic("Couldn't connect to server")

	}

	defer thing.Disconnect(ctx)

	// This publishes to /events

	thing.PublishEvent(ctx, []byte("Top level telemetry event"))

	// This publishes to /events/a

	thing.PublishEvent(ctx, []byte("Sub folder telemetry event"), "a")

	// This publishes to /events/a/b

	thing.PublishEvent(ctx, []byte("Sub folder telemetry event"), "a", "b")

}

```
