Retention Flow Tables and Sankey Diagrams

Creates transition tables, summaries, and interactive Sankey diagrams from longitudinal person-term-state data. Sankey diagrams visualize flows between states with link widths proportional to flow counts; see Kennedy and Sankey (1898) "The Thermal Efficiency of Steam Engines" and Schmidt (2008) "The Sankey Diagram in Energy and Material Flow Management: Part I: History" . The minimum input schema is one row per person per term with an identifier, term, and categorical state.
