Summary description: Numerical physics models with Forrester diagrams and auto-sized plots
Announcement text: ----------------------------------------------------------------------
First CTAN release of numodel-bundle (v0.2.0).
numodel-bundle is a LuaLaTeX package for writing and rendering numerical models (Euler-integrated dynamical systems) directly inside LaTeX documents, aimed at physics teaching material.
The bundle ships two modules:
* numodel -- modelling engine: text-mode rule tables, Forrester stock-and-flow diagrams (tight/forrester/edu styles), numerical simulation in Lua, y(x)-plot integration. * numodel-plot -- PGFPlots styling layer that auto-sizes plots to a clean tick lattice; configurable axis-label formats (IEEE, ISO 80000-1).
Pre-1.0 release; breaking changes still possible before 1.0.0.
