- Introduced `GeomGridEval` package with specialized evaluators for analytical surfaces (plane, cylinder, sphere, cone, torus) and parametric surfaces (Bezier, BSpline, offset) - Refactored extrema computation in `Extrema_GenExtSS`, `Extrema_GenExtPS`, and `Extrema_GenExtCS` to use batch grid evaluation - Added comprehensive derivative computation support (D0-D3, DN) for all surface types
