API to dynamically add and remove bindings

[wkeese]

The Bind() function creates an "observable Object" (the return value from the function) and sets up bindings to other Objects (often DOM nodes). But AFAICT there's no way to dynamically add or remove bindings to an existing "observable Object". Something like:

var user = Bind({ first: "Bob", last: "Jones"});
user.bind("first", "#first");
user.bind("last", "#last");

The reason that would be nice is for code decoupling, i.e. so various pieces of code that don't know about each other can attach to user.

I'd be up for a PR to add that functionality, but perhaps it should be inside of the Bind method instead of on the object, i.e.

var user = Bind({ first: "Bob", last: "Jones"});
Bind.update(user, { age: 30, location: 'foo' }, { age: '#age', location: { ... });
