Release 0.7.0

Release 0.7.0 is a major release with fundamental changes to the diagram extension. It also introduces an intermediate MarkupMachine which can be used to transfer and (re-)initialize machine configurations.

• Feature #263: MarkupMachine can be used to retrieve a Machine's dictionary representation
  • GraphMachine uses this representation for Graphs now and does not rely on Machine attributes any longer
• Feature: The default value of State.ignore_invalid_triggers changed to None. If it is not explicitly set, the Machine's value is used instead.
• Feature #325: transitions now supports pygraphviz and graphviz for the creation of diagrams. Currently, GraphMachine will check for pygraphviz first and fall back to graphviz. To use graphviz directly pass use_pygraphiv=False to the constructor of GraphMachine
• Diagram style has been overhauled. Have a look at GraphMachine's attributes machine_attributes and style_attributes to adjust it to your needs.
• Feature #305: Timeouts and other features are now marked in the graphs
• Bugfix #343: get_graph was not assigned to models added during machine runtime
