Make storing objects in SessionStorage easier and faster.

ob-session

File size of all components combined

The ob-session package contains three refeences to make storing objects in SessionStorage easier and faster:

1. A small "api" that enhances the sessionStorage.setItem, sessionStorage.getItem and sessionStorage.removeItem calls to support storing objects, not just strings, in a performant way. Objects are stored in a global cache for rapid retrieval, but a stringified version is stored in sessionStorage for when the page is refreshed.
2. A non-visual web component, "ob-session-watch", that watches for sessionStorage changes, and fires an event when such a thing happens. It can watch for all changes, or to those with a specified key.
3. A non-visual web component, "ob-session-update", that updates sessionStorage declaratively.

Why focus on Session Storage?

Whereas one could argue that local storage is being eclipsed by helper libraries based on Indexed DB, session storage serves a particular niche -- In some lines of business, caching business data in the client, even after the browser closes, runs afoul of audits. history.state and sessionStorage don't appear to raise such concerns.
