Sides of affine subspaces

This file defines notions of two points being on the same or opposite sides of an affine subspace.

Main definitions

• s.WSameSide x y: The points x and y are weakly on the same side of the affine subspace s.
• s.SSameSide x y: The points x and y are strictly on the same side of the affine subspace s.
• s.WOppSide x y: The points x and y are weakly on opposite sides of the affine subspace s.
• s.SOppSide x y: The points x and y are strictly on opposite sides of the affine subspace s.
