Code changes

  • PatchLoading vertex validation is now cyclic-rotation-aware.

  • NumPy-style docstrings added to all public functions and classes.

  • Dead code removed from Analysis.__init__ (9 obsolete command-string attributes, analysis_arguments dict).

  • Envelope.get() rewritten without eval().

  • Minimum supported Python version raised from 3.9 to 3.10.

  • 30 new tests added; overall coverage rises from 71 % to 75 %.

Documentation overhaul

  • Navigation restructured into four top-level sections: Getting Started, User Guide, API Reference, and Additional Resources.

  • API reference split into per-module pages; Load module further subdivided into load types, load cases, and moving loads.

  • All source files renamed to match their page titles; source folder renamed rst/ → pages/.
