> Avoiding a singleton for Configure will allow us to eventually support multiple, disparate
flows. The object FlowConfiguration can be passed with the information in Configure. This
has increased coupling dramatically while also limiting how configurations can be stored within
> It stands to reason that to eventually support C2 activities and to facilitate multiple
configurations, we will need to remove state from the global level and make it something that
is referenced from the objects which care ( proper encapsulation ).
