description:
Added python wrapper for down_cast.
Usage:

u = Vector()
v = down_cast(u, PETScVector)

is the same as

Vector u;
PETScVector & v = u.down_cast<PETScVector>();

If people are happy with this, we can remove the
"as_foo" functions I added earlier.

The implementation uses a small python dict to map the
class argument to a helper function that calls
the right instantiation of the template member
function GenericTensor::down_cast<T>().

description:
Added instance() to GenericTensor so it can be used by down_cast<T>().
Changed down_cast to return a reference instead of pointer.
Cleaned up instance() implementations (all return GenericFoo* now).
