- Auto-sizing of plot. No longer any need to explicitly declare size or origin.
- Remove need to declare :class:`Node`, :class:`Edge`, or :class:`Plate` classes when calling
``add_node()``, ``add_edge``, or ``add_plate``. Should simplify syntax.
- Can now style (offset, rotation) :class:`Edge` annotations as ``label`` param, additional
parameters passed through as ``label_params`` to :class:`matplotlib.axes.Axes.annotate`.
- Add `alternative` node style as an option for unobserved parameters.
- Fix default ``bbox`` ``facecolor`` to be 'none'.
- Fix various ``dict`` params when default is ``None``.
- Fix types of passed params to ensure cast to ``float``.
- Update examples and documentation. Documentation will now auto-build by Travis.
