Implements annotations, intervals, and error bars and adds basic tests for functionality.
Currently intervals render poorly due to layering by Google Charts. That is, annotations for a bar can be covered up by the next bar, which is drawn on top. Fixing this may require a hack or a switch in libraries, which I'm not up to doing.
