WIP based on Choice modelling and Mark Paich's Book and NZ work focus on Pre-ED Presentation choices, with ED and Post-ED care. Extended based on IM-998 4 hour rule context. Can be replicated to add interventions, as in IM-6167. See IM-9178 for Addition of After hours 'as is' and 'to be' flow models for Medicare Locals
