Ok I understand the second group of errors then. But the Function.h
interface is made using the Vector and not uBlasVector, so how can I use
both the constructor dolfin::Function::Function(dolfin::Mesh&,
dolfin::Vector&, const dolfin::Form&, dolfin::uint) and not lose the
functionalities of uBlas? Thanks.
