Created whole new system

This is an entirely new Telescopic Text system. It has all of the
functions of the old TText, but has many other capabilities:

- Branches of the tree can now intersect.
- The tree is fully represented as instances of Node in state.
Subclasses are Ttext and Hhtml.
- Node instances have limited intelligence of what is above and below
them.
- Nodes can contain HTML snippets, which allows you to embed images,
media, or pretty much whatever you want.
- Hhtml nodes group and wrap their children with their html tags. It's
useful for formatting and declaring a bunch of nodes to be of class foo.

-There's still alot of work to be done here. This works, but the next
step is to do a re-write to separate the DOM and State.  There are
comments on how to do this at the top of node.coffee.
