Adds support for creating state machines for attributes on any Ruby class

StateMachine::Graph#add_nodes

Adds a new node to the graph.  The font for the node will be automatically
set based on the graph configuration.  The generated node will be returned.

For example,

  graph = StateMachine::Graph.new('test')
  graph.add_nodes('parked', :label => 'Parked', :width => '1', :height => '1', :shape => 'ellipse')
