Checklist

Put an x in the boxes that apply. You can also fill these out after creating the PR. If you're unsure about any of them, don't hesitate to ask. We're here to help! This is simply a reminder of what we are going to look for before merging your code.

• [ ] I added a line to the CHANGELOG.md file in the Unreleased section under the most fitting heading (e.g. Added, Changed, Removed).
• [ ] I ran all tests on my computer and it's all green (i.e. invoke test).
• [ ] I ran lint on my computer and there are no errors (i.e. invoke lint).
• [ ] I added new functions/classes and made them available on a second-level import, e.g. compas.datastructures.Mesh.
• [ ] I have added tests that prove my fix is effective or that my feature works.
• [ ] I have added necessary documentation (if appropriate)

Some explanation...

• compas.geometry.surfaces.surface.Surface is like an ABC for parametric surfaces.
• compas.geometry.surfaces.surface.Surface.__new__ has been replaced such that only subclasses can be instantiated.
• __new__ re-overwrites of subclasses are therefore no longer necessary.
• Surface has many implementations (Conical, Cylindrical, Planar, Spherical, Toroidal, Nurbs). only NurbsSurface requires a plugin implementation.
• from_native has been added to Surface since CAD engines can provide a "native" surface from which all parametric functionality can be derived, even without knowing what kind of surface it is.
• all specific factory methods have been moved to NurbsSurface since they indeed produce a Nurbs surface.
• elementary surfaces can be instantiated directly from the specific pure Python classes (ConicalSurface, CylindricalSurface, ...)
• a few small bugs have been fixed along the way.
• similar changes should be made to the Curve API...

all of this has been tested with OCC as plugin and using the viewer for visualisation. Rhino should still be verified.
