Summary:
I'd like to be able to access the current collection view scrolling traits inside section controllers. These are expressed as three properties from `UIScrollView`:
`isTracking`, `isDragging`, and `isDecelerating`.
My approach is to add a new struct `IGListCollectionScrollingTraits` with these three values, and expose this to section controllers through `IGListCollectionContext`.

Summary:
I had a desire for interactive reordering in a personal project, so here's a first attempt at adding support in IGListKit.
I figured I might as well get a WIP PR up for comments before I continue further as there are a few aspects to interactive reordering that don't interplay perfectly with IGListKit.
As discussed in #291, I went after two prime use cases:
1. Moving items amongst a section
2. Rearranging whole sections
I also "disabled" moving items between sections by having those moves revert, to mimic interactive reordering cancellation as closely as possible.
You can see both in the Mixed Data example. Grid items can be moved within a section, while users can be moved to reorder whole sections. But trying to move a grid item out of a grid or a user item into a grid will auto-revert. The revert animation isn't as tight as it should be. It may be more desirable to disable the animation - though you lose the visual cue.
There is a also a new example, `ReorderableViewController`, that demonstrates 2 in its pure form (likely the most desired use case), where all sections are reorderable single rows.
Happy to take feedback -- this is my first experience working on IGListKit, so I would expect there to be gaps. (Ex. I haven't used `IGListStackedSectionController`, and its tests failed as I hadn't implemented reordering delegates for it. Those are simply stubbed out for now.)

Followup from #1068
The `NSIndexPath` methods we use **are not** available <10.11. In theory this has always been "broken" b/c older macOS versions would crash at runtime when trying to use these methods.
Normally this would be breaking change, but I can't imagine anyone is using IGListKit on the mac targeting 10.10 and shipping a working app.

This should be the last remaining item before we get a green badge.
(note that 10.11 was released 9/30/15 which is about 2 weeks before the public IGListKit release)

- Given a top-level object, transform it into an array of **diffable** view models
- Given a view model, return a cell
- Given a view model, return a size for a cell
- A new protocol for the cell `IGListBindable` so that we can control when the cell is updated w/ the view model.

Summary:
So the main Podspec file now has two Subspecs, `Diffing` and for lack of better name `Default`. `Diffing` is purely the files within the common directories (used for Diffing, if in the future we support MacOS NSCollectionView then this may need changing). `Default` depends on `Diffing` but also adds all the non-common files.
To use it via CocoaPods, nothing changes. You `import IGListKit` and you will only have access to the files in the pod you use. (So if you use `IGListKit/Diffing` in your Podfile, then you will only get access to the diffing files). If you do a manual installation, or I assume via Carthage, then you will need to import the correct header file (either `IGListDiffKit.h` or `IGListKit.h` depending on what you want).
Turns out CocoaPods creates it's own umbrella header (unless you tell it otherwise) meaning our ones are unused by it.
Just to confirm `IGListKit` in your Podfile will give you everything, only if you add `/Diffing` will you "opt-out" o
