Start VectorSpaceBasis.h. Doesn't compile yet, SWIG is failing
for some reason.
Need to include it in dolfin_la.h.
A skeleton VectorSpaceBasis.cpp
Stubs for the rest of the functions
Some stubs to make it compile, at least
Implement orthonormality check.
Implement orthogonalize.
More VectorSpaceBasis work
Get the C++ singular demo to work with VectorSpaceBasis
Try to use the new VectorSpaceBasis from Python. SWIG problems.
Check the residual in the C++ demo.
Change to Johan's suggestion for how to represent a list of Vectors
in C++.
Ah! Working at last. Got the C++ and Python demos working,
with Johan's help.
Apply Johan's patch to avoid copying in the C++ singular demo
check_orthonormality -> is_orthonormal.
Minor changes.
Rename VectorSpaceBasis::operator[] in Swig layer.
