transpose one gradient matrix.  This makes the code run, but it still doesn't work even for RealTuple<1>

export the manifold dimension as 'dim'.  The main class template parameter had to change names for this

[[Imported from SVN: r6433]]

The first dim rows contain an orthonormal frame of the tangent space
as before.  The new rows contain an orthonormal frame of the
normal bundle.

Make the space to be tested a parameter.  Unlike originally envisioned this test should not just test the UnitVector class
