Modifications for new matrix classes. Warning: the old hpsolve() method
for solving linear systems with high-precision (LU factorization and then
iterative improvement) has been replaced by a call to PETSc. This might
result in lower accuracy for computation of Gauss points and cG(q)/dG(q)
weights. Needs to be examined more closely.

All old linear algebra should now be removed. Everything is now PETSc.

The following classes are wrappers for PETSc linear algebra:

Matrix, Vector, VirtualMatrix
GMRES, LU, Preconditioner
