[annotator-dev] annotator2/master storage configuration

[Benjamin Young]

Hey Andrew,

I'm guessing your wanting to use the HTTP Storage implementation (since you
mention endpoint configuration). If that guess is correct, you would do it
something like this:

```
anno.setStorage(function() {
  return new HTTPStorage({
    prefix: '/url/to/your/endpoint'
  });
});
```

Essentially, setStorage expects a function that will return a storage
implementation (which amounts to an object with functions for create,
update, delete, and query; see the DebugStorage code [1] for a simple
example). HTTPStorage ships with annotator and assumes that you're using
something compatible with the annotator-store project [2].

So, in effect, you create a new HTTPStorage object inside a closure that
setStorage will use when it sets things up for create, update, etc.

The indirection can be a little confusing, but it does provide a way for
you to test your storage code without any additional setup (as they're
generally just plain JS functions and objects.

Hope that helps!
Benjamin
