daft v0.1.0

0.1.0 (2019-09-16)
++++++++++++++++++

• 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.
