ReflectionMatrix
gives the matrix that represents reflection of points in a mirror normal to the vector v.
Details

- The reflection is in a mirror that goes through the origin.
- ReflectionMatrix works in any number of dimensions. In 2D it reflects in a line; in 3D it reflects in a plane.

Points in the reflection plane remain fixed:
Points outside the reflection plane get reflected in the plane:
