/*!(

The most notable ways to improve this include:

* setting a reasonable lower quota limit or probing for upper cookie storage limits and throwing an error when trying to assign above quota, like the LocalStorage/SessionStorage APIs

* checking to see if window.navigator.cookieEnabled equals true before writing, throw an error when trying to use cookieStorage if cookieEnabled is false. We treat it as though it were a disabled permission, as it is.

* I would probably not format my code like this any more.
