Option to add an offset/padding

[luxzeitlos]

On the demo site there is an offset between the tooltip and the target:

But when I tried to implement the tooltip I never get this offset:

So I think some documentation is missing here at least. Any help about this?
I've realized there is an undocumented isOffset feature in the code. Also the corresponding test uses margin-bottom, which works, but breaks when the popper flips. What is the recommended way to do this, and can this please be documented somewhere?

Hey @luxferresum, I'll write something up for you soon, just a little swamped playing catch-up on work after a brutal week-long cold.

Here's a brief summary of how the offset works:

The attachment is actually two containers, an outer container for the positioning addon, ember-popper, and an inner container for the animations.

The outer container is set up just like you'd expect, positioned right next to the target. It is the inner container that is implementing the offset.

The default animations for ember-attacher do this with a CSS transform property on the inner container:

• https://github.com/kybishop/ember-attacher/blob/master/addon/styles/_mixins.scss#L88

transform is the CSS magic that allows our animations to smoothly shift up/down, left/right, etc.

I have documented this a little more thoroughly in the README when talking about how animations are implemented. Hopefully this clears up confusion over the perceived offset.
