SWIG does not seem to wrap operators by default but the other things
are there.

Try doing

>>> A = uBlasDenseMatrix(10, 10)
>>> dir(A)

You should get something like

['__class__', '__del__', '__delattr__', '__dict__', '__doc__',
'__getattr__', '__getattribute__', '__hash__', '__init__',
'__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__',
'__setattr__', '__str__', '__swig_getmethods__',
'__swig_setmethods__', '__weakref__', '_s', 'add', 'apply', 'disp',
'getRow', 'ident', 'init', 'invert', 'label', 'lump', 'mult', 'name',
'number', 'nzmax', 'rename', 'set', 'size', 'solve', 'this',
'thisown', 'zero']

I don't know SWIG very well but I guess we need some further glue to
map __call__ to operator() and __repr__ to dolfin::cout << so one can
do things like

    A(5, 5) = 0.5

or

    print A

and get the expected results.
