description:
Add constructors to uBlasDenseMatrix and uBlasSparseMatrix.

I've removed the compilation flag -DNDEBUG when using --enable-debug, so uBlas operations will be extremely slow when using --enable-debug.

description:
Update interface for ODE solvers to use uBlas vectors.
Only the interface has changed. The internal representation
and solvers are still PETSc vectors. The solvers have been
tested on a number of the demo problems, but not all demos
have been ported to the new interface. A lot of editing is
needed. The speed seems to remain the same.

The new interface is either

    void f(const DenseVector& u, real t, DenseVector& y)

for the mono-adaptive solvers or

    real f(const DenseVector& u, real t, uint i)

for the multi-adaptive solvers.

The next step is to use uBlas vectors and solvers internally.
