Hi all,

I am working on revising the class structure for generic curves to make it 
easier to implement functionality for the GSoC 2016 project on algebraic 
curves. The main curve classes right now are ProjectiveSpaceCurve_generic, 
ProjectiveCurve_generic, AffineSpaceCurve_generic, and AffineCurve_generic, 
with ProjectiveCurve_generic and AffineCurve_generic representing plane 
curves. The implementations of these classes reside in 
/schemes/plane_curves.

Currently, the plane curve classes do not inherit from the space curve 
classes and there isn't any functionality specific to the space curve 
classes. The goal of ticket #20697 <http://trac.sagemath.org/ticket/20697> is 
to make the plane curve classes inherit the space curve classes so that the 
space curve classes act as the generic classes for projective/affine 
curves. However, doing this makes the class names a bit inaccurate, since 
for example the ProjectiveCurve_generic class really represents plane 
curves and ProjectiveSpaceCurve_generic is the more general class. It seems 
that it would be a lot clearer to have a different naming scheme, such as 
having ProjectiveCurve_generic be called ProjectiveCurve_plane, and having 
ProjectiveSpaceCurve_generic be called ProjectiveCurve_generic (similarly 
for the affine curve classes).

Is there a policy for changing class names in Sage? Also, since there 
eventually will be more functionality implemented for generic curves and 
not just plane curves, would it be possible to rename the plane_curves 
folder to something more general such as "curves" or "curves_generic"?

Thank you,
Grayson
