Projection of Vector on Plane via Geometric Algebra

This construction tests formulas derived via Geometric Algebra for the projection of a vector on a plane from an arbitrary angle (not just the vector's perpendicular projection). The formulas are derived in the document "Projection of a Vector upon a Plane from an Arbitrary Angle, via Geometric (Clifford) Algebra",
