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

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.

For this now the TangentVector class of S^n has only n components,
while the EmbeddedTangentVector class still has n+1.
The code around it needs to be fixed accordingly.
