I would like to add factory functions in UFC, in particular

Are there any objections to this? It would be easy to add and easy to
implement in FFC.
I need it to implement refinement of FunctionSpaces in DOLFIN where
fresh copies of ufc::finite_element and ufc::dof_map are needed given
a ufc::finite_element or ufc::dof_map.
An alternative is to hack create_sub_foo so that it returns a copy of
the element/dofmap itself if the component argument 'i' is>= the
number of sub elements/dofmaps.
I suggest we add this to UFC 1.6 and make a release next week together
with DOLFIN 0.9.10, FFC 0.9.5 + other packages that need release. The
sooner the better: there will be time to make bug fix releases and
things will be tested before 1.0 in March.
If there are any other things we want to add to UFC, now's a good
time.
What about the tabulate_tensor function taking arguments for runtime
quadrature rules, as we discussed a while ago? ATM I hacked UFC and
my generated form files having an additional function
virtual void tabulate_tensor(double* A,
const double * const * w,
const ufc::cell& c,
dolfin::uint num_quad_points,
const double * const * coordinates,
const double * weights) const
Such an interface would add a flexible layer for those who wants to
have some type of runtime quadrature.
General opinons about that?
