How can I position windows with the maximize button? I was watching this video when the instructor was able to position a window by using the maximize button and clicking on one of four positioning options, as seen in the image below. 



This was also not specific to the program, as it was done in different windows for different applications.

Is this a native OS X feature? If so, which settings were enabled? If not, are there known applications allowing for this feature?
This looks like Moom which Is available from the App Store
