Setting the weather, plugging in the data

//Setting the weather, plugging in the data

// Right now we're getting weather data,
// when the activity is created, which is when the app starts up.
// That's great, but we can't expect our users to close out the app completely, and
// start it up every time they want to get the latest weather.
// We need to give them a way to update the weather.
// Currently, we are just logging the response from forecast down here in
// the on response call back.
// Let's add a new method, to update the display.
