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.

That makes the code more readable, which is more important to me than
speed.  The stuff is difficult enough as it is.
