How to install OS X Yosemite in Virtualbox with Yosemite Zone

We've previously shown you how to install OS X Mavericks on a virtual machine by using Niresh, which is great practice for installing Mac OS X on your actual computer. And now that Apple has released OS X Yosemite, it's only fitting that we show you how to install Yosemite in a virtual machine as well. For this guide, we'll be using the "Yosemite Zone" distro, which is really just a rebranded version of the old Niresh distro that we used in our Mavericks guide. While we've already shown you how to install Yosemite on your actual computer with Yosemite Zone, it also works great with virtual machines.
