add an example.

This is how I think it should work.

Obviously Tom had something different in mind, and this does not work yet :)

Merge pull request #3 from tardyp/master

- Removed implicit configuration from scope: scope may be shared with other directive so, I think it is a bad practive
- Remove configuration from scope.config(). Again this is a generic name, directive should not use it.
- added a prefix for all attributes, so that it does not clash with html, or other directives
- wait for the scope to settle before instantiating the charts, so that the controller can asynchronously load the data.
