Google Now finally allows voice commands to 'Send a Hangouts Message'

It is finally possible to send message in Hangouts using Google Now voice commands.

Gone are the days of having to pick up your phone and actually type a message to your friends on Hangouts; now you can simply use Google Now to send it. All you have to do is launch Google Now then say "send a Hangouts message." It will then ask who you want to send to and what you want the message to say, then confirm that you want to send it.
