The goal of 'readsdr' is to bridge the design capabilities from
specialised System Dynamics software with the powerful numerical tools
offered by 'R' libraries. The package accomplishes this goal by parsing
'XMILE' files ('Vensim' and 'Stella') models into 'R' objects to construct
networks (graph theory); 'ODE' functions for 'Stan'; and inputs to simulate
via 'deSolve' as described in Duggan (2016)
